Ah, thanks for explaining it.
Yes, I'm proposing that '--changelist foo' just add more targets to
the master list of targets, the same way that '--targets filename'
does. So in the end, the targets to a command can come from any
combination of three sources: --targets, --changelist, and ones that
are hand-typed on the commandline.

What's would be the motivation to make this API streamy? It can't be
a matter of 'perceived user response time' (a la 'svn status'),
because we're just gathering targets to feed to the subcommand,
there's nothing to print. Is it a matter of trying to bound memory
usage? I don't think that's relevant here either, since every
subcommand always holds the whole array of targets in memory anyway
(which we're just augmenting with some crawl results).
