Well, I won't rush into it.  But the "revision" completion is fairly 
complex, and likely to get worse as I add support for the automatic 
aliases, e.g.

Fai> nget t[TAB]
tmod
tcur
address@hidden

Fai> nget tcur:[TAB]
[list of archives, packages, versions]

err, so that it shows just category names when you hit [TAB][TAB]?

Considering the intended use, more human-readable is how I'd lean.

Well, I'm thinking output formats might be "diffs", "archives", 
"packages", "package-versions", "revisions"...

Sounds neat.

Sure thing.  Else, I'd have said "I've applied that fix". :-)
