revert: improve hints on abort when reverting to parent without --all

BEFORE:

    $ hg revert
    abort: no files or directories specified
    (use --all to discard all changes)

AFTER:

  Uncommitted changes (using --all *will* nuke edits):

    $ hg revert
    abort: no files or directories specified
    (uncommitted changes, use --all to discard all changes)

  Clean working directory (using --all won't discard anything):

    $ hg revert
    abort: no files or directories specified
    (use --all to revert all files)

#!/usr/bin/env python
# Dump revlogs as raw data stream
# $ find .hg/store/ -name "*.i" | xargs dumprevlog > repo.dump
