lfs: correct documentation typo

test-convert-svn-move: sort svn checkout output It turns out that there's no guarantee in which order svn will traverse a directory while performing a checkout. Sorting the output will make these tests stable.

fileset: do not crash by unary negate operation Backported from minifileset.py.

fileset: make it robust for bad function calls Before, it could crash or show cryptic message.

log: build follow-log filematcher at once We no longer need to replay copy tracing to build filematcher as we can walk (rev, fctxs) pairs.

log: allow matchfn to be non-null even if both --patch/--stat are off This makes the next patch slightly simpler.

log: replace "not pats" with matcher attribute for consistency We use match.always() in _makelogrevset(). match.always() is identical to "not pats" here since scmutil.matchandpats() empties pats in that case.

log: follow file history across copies even with -rREV (BC) (issue4959) Still it falls back to changelog path if glob patterns or missing paths are specified. This will be changed later. .. bc:: ``log --follow -rREV FILE..`` now follows file history across copies and renames.

log: resolve --follow thoroughly in getlogrevs() This makes sense because --follow isn't really an option to filter revisions, but an option to extend revisions to be filtered. _fileancestors() is a minimal copy of revset._follow(). They are slightly different in that which revision the matcher sees. _fileancestors() also uses ctx.walk() instead of ctx.manifest().walk() to show a better warning on bad match, which will be tested later.

log: extract function that processes log file patterns We'll need a matcher to compute revs followed from the given patterns.
