largefiles: for update -C, only update largefiles when necessary...
largefiles: for update -C, only update largefiles when necessary Before, a --clean update with largefiles would use the "optimization" that it didn't read hashes from standin files before and after the update. Instead of trusting the content of the standin files, it would rehash all the actual largefiles that lfdirstate reported clean and update the standins that didn't have the expected content. It could thus in some "impossible" situations automatically recover from some "largefile got out sync with its standin" issues (even there apparently still were weird corner cases where it could fail). This extra checking is similar to what core --clean intentionally do not do, and it made update --clean unbearable slow. Usually in core Mercurial, --clean will rely on the dirstate to find the files it should update. (It is thus intentionally possible (when trying to trick the system or if there should be bugs) to end up in situations where --clean not will restore the working directory content correctly.) Checking every file when we "know" it is ok is however not an option - that would be too slow. Instead, trust the content of the standin files. Use the same logic for --clean as for linear updates and trust the dirstate and that our "logic" will keep them in sync. It is much cheaper to just rehash the largefiles reported dirty by a status walk and read all standins than to hash largefiles. Most of the changes are just a change of indentation now when the different kinds of updates no longer are handled that differently. Standins for added files are however only written when doing a normal update, while deleted and removed files only will be updated for --clean updates.

interactively select changes to commit
If a list of files is omitted, all changes reported by "hg status" will be
candidates for recording.
See "hg help dates" for a list of formats valid for -d/--date.
You will be prompted for whether to record changes to each modified file,
and for files with multiple changes, for each change to use. For each
query, the following responses are possible:
y - record this change
n - skip this change
e - edit this change manually
s - skip remaining changes to this file
f - record remaining changes to this file
d - done, skip remaining changes and files
a - record all changes to all remaining files
q - quit, recording no changes
? - display help
This command is not available when committing a merge.
options ([+] can be repeated):
-A --addremove mark new/missing files as added/removed before
committing
--close-branch mark a branch as closed, hiding it from the branch
list
--amend amend the parent of the working directory
-s --secret use the secret phase for committing
-e --edit invoke editor on commit messages
-I --include PATTERN [+] include names matching the given patterns
-X --exclude PATTERN [+] exclude names matching the given patterns
-m --message TEXT use text as commit message
-l --logfile FILE read commit message from file
-d --date DATE record the specified date as commit date
-u --user USER record the specified user as committer
-S --subrepos recurse into subrepositories
-w --ignore-all-space ignore white space when comparing lines
-b --ignore-space-change ignore changes in the amount of white space
-B --ignore-blank-lines ignore changes whose lines are all blank
