 Merge largefiles into lfs branch
 
 The largefiles extension will prompt to use the normal or largefile when merged
 into the lfs files.  `hg manifest` will show standins if present.  They aren't,
 because largefiles merge doesn't merge content.  If it did, selecting (n)ormal
 would convert to lfs on commit, if appropriate.
 
 BUG: Largefiles isn't running the merge tool, like when two lfs files are
 merged.  This is probably by design, but it should probably at least prompt if
 content should be taken from (l)ocal or (o)ther as well.

 When both largefiles and lfs are configured to add by size, the tie goes to
 largefiles since it hooks cmdutil.add() and lfs hooks the filelog write in the
 commit.  By the time the commit occurs, the tracked file is smaller than the
 threshold (assuming it is > 41, so the standins don't become lfs objects).

   lfs.txt
   normal.txt
 
   $ hg rm large_by_size.bin
   $ hg ci -m 'remove large_by_size.bin'
 
 Largefiles doesn't do anything special with diff, so it falls back to diffing
 the standins.  Extdiff also is standin based comparison.  Diff and extdiff both
 work on the original file for lfs objects.

 convert extension under the hood with --to-normal.  So the --config based

   additional optimizations are available by specifying "--optimize <name>":
   
   re-delta-parent
      deltas within internal storage will be recalculated to choose an optimal base revision where this was not already done; the size of the repository may shrink and various operations may become faster; the first time this optimization is performed could slow down upgrade execution considerably; subsequent invocations should not run noticeably slower
   
   re-delta-multibase
      deltas within internal storage will be recalculated against multiple base revision and the smallest difference will be used; the size of the repository may shrink significantly when there are many merges; this optimization will slow down execution in proportion to the number of merges in the repository and the amount of files in the repository; this slow down should not be significant unless there are tens of thousands of files and thousands of merges
   
   re-delta-all
      deltas within internal storage will always be recalculated without reusing prior deltas; this will likely make execution run several times slower; this optimization is typically not needed
   
   re-delta-fulladd
      every revision will be re-added as if it was new content. It will go through the full storage mechanism giving extensions a chance to process it (eg. lfs). This is similar to "re-delta-all" but even slower since more logic is involved.

   repository lacks features recommended by current config options:
   
   fncache
      long and reserved filenames may not work correctly; repository performance is sub-optimal
   
   dotencode
      storage of filenames beginning with a period or space may not work correctly
   
   generaldelta
      deltas within internal storage are unable to choose optimal revisions; repository is larger and slower than it could be; interaction with other repositories may require extra network and CPU resources, making "hg push" and "hg pull" slower
   
   sparserevlog
      in order to limit disk reading and memory usage on older version, the span of a delta chain from its root to its end is limited, whatever the relevant data in this span. This can severly limit Mercurial ability to build good chain of delta resulting is much more storage space being taken and limit reusability of on disk delta during exchange.

      added: dotencode, fncache, generaldelta, sparserevlog (no-rust !)
      added: dotencode, fncache, generaldelta, persistent-nodemap, sparserevlog (rust !)
   
   fncache
      repository will be more resilient to storing certain paths and performance of certain operations should be improved
   
   dotencode
      repository will be better able to store files beginning with a space or period
   
   generaldelta
      repository storage will be able to create optimal deltas; new repository data will be smaller and read times should decrease; interacting with other repositories using this storage model should require less network and CPU resources, making "hg push" and "hg pull" faster
   
   sparserevlog
      Revlog supports delta chain with more unused data between payload. These gaps will be skipped at read time. This allows for better delta chains, making a better compression and faster exchange with server.

   additional optimizations are available by specifying "--optimize <name>":
   
   re-delta-parent
      deltas within internal storage will be recalculated to choose an optimal base revision where this was not already done; the size of the repository may shrink and various operations may become faster; the first time this optimization is performed could slow down upgrade execution considerably; subsequent invocations should not run noticeably slower
   
   re-delta-multibase
      deltas within internal storage will be recalculated against multiple base revision and the smallest difference will be used; the size of the repository may shrink significantly when there are many merges; this optimization will slow down execution in proportion to the number of merges in the repository and the amount of files in the repository; this slow down should not be significant unless there are tens of thousands of files and thousands of merges
   
   re-delta-all
      deltas within internal storage will always be recalculated without reusing prior deltas; this will likely make execution run several times slower; this optimization is typically not needed
   
   re-delta-fulladd
      every revision will be re-added as if it was new content. It will go through the full storage mechanism giving extensions a chance to process it (eg. lfs). This is similar to "re-delta-all" but even slower since more logic is involved.
