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

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)
