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)
