It seems to me this utility is a bit misnamed; while it can be used to undo
changes to a file, it works more like cvs log. Suggestions for a better name
collected on irc include

fslog/filelog
hammer log (it _is_ hammer-specific, right?)
hist (a la http://swtch.com/plan9port/man/man1/hist.html)

I hate to start another thread that's likely to degenerate in a
crazy-idea-contest, but now there is still time to change undo to something
more intuitive (if everybody agrees there is a problem) without breaking any
users...
