I noticed that with the latest StGit:
# stg diff -r /bottom
stg diff: /bottom: Unknown patch or revision name

Before I bisect to find where this disappeared, is there a different 
syntax I should be using?

Thanks,
Dan

In the development (master) branch, we changed the syntax to make it
cleaner. A patch (its top) can be identified as [<branch>:]<patch>. It
also supports standard Git suffixes like ^, ~{...} etc. To access the
bottom of a patch, just use [<branch>:]<patch>^.

The bottom of the top patch could be accessed as HEAD^ (I've been
thinking about only allowing the caret for this, without the HEAD but
I didn't have time to try it).
