revert: mention update in hint of abort when reverting to non-parent and explicitly warn about uncommitted changes Examples: BEFORE: $ hg par -q 7:e81a2efd53d4 $ hg revert -r 2 abort: no files or directories specified (use --all to discard all changes) AFTER: Clean working directory (revert can be easily undone, no edits to be lost): $ hg revert -r 2 abort: no files or directories specified (use --all to revert all files, or 'hg update 2' to update) Uncommitted changes (revert --all *does* discard edits and is pretty hard to undo or even impossible if --no-backup is specified): $ hg revert -r 2 abort: no files or directories specified (uncommitted changes, use --all to discard all changes, or 'hg update 2' to update)

update: clarify that update changes the parent revison

merge with stable

revset: fix aliases with 0 or more than 2 parameters The existing code seemed to have incorrect assumptions about how parameter lists are represented by the parser. Now the match and replace functions have been merged and simplified by using getlist().

match: fix bug caused by refactoring in cfc89398f710

revert: be more helpful on uncommitted merges BEFORE: $ hg revert abort: no files or directories specified (use --all to discard all changes) AFTER: $ hg revert abort: no files or directories specified (uncommitted merge, use --all to discard all changes, or 'hg update -C .' to abort the merge)
