 Merge post-processing
 
 cat is a bad merge-tool and doesn't change:
 
   $ beforemerge
   [merge-tools]
   false.whatever=
   true.priority=1
   true.executable=cat
   # hg update -C 1
   $ hg merge -y -r 2 --config merge-tools.true.checkchanged=1
   merging f
   revision 1
   space
   revision 0
   space
   revision 2
   space
    output file f appears unchanged
   was merge successful (yn)? n
   merging f failed!
   0 files updated, 0 files merged, 0 files removed, 1 files unresolved
   use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon

 internal merge cannot handle symlinks and shouldn't try:
 
   $ hg update -q -C 1
   $ rm f
   $ ln -s symlink f
   $ hg commit -qm 'f is symlink'
   $ hg merge -r 2 --tool internal:merge
   merging f
   warning: internal:merge cannot merge symlinks for f
   merging f incomplete! (edit conflicts, then use 'hg resolve --mark')
