I see your point but I thought "--clean" was pretty descriptive of how
the working dir ended up afterward. Maybe "git stash --everything" (or
"--all")?

Yes, in that case you are right. My example was poor. I'm more worried
about junk that might actually affect the release but isn't
auto-generated. I'm usually too wary to run "git clean" because of the
random files I have sitting around--todo lists, random patches, new
files I haven't added but are sitting around possibly affecting tests,
things like that. I want them back at some point, but I want the
directory very clean when doing the release just to make sure I have
everything properly committed (so I could, for example, detect the new
source file that I forgot to add and commit).

Yes, you'd definitely want the git clean before the git stash pop. I
forgot that step.

Whoops. That was a copy and paste error. Took multiple tries to get git
send-email to work ;-).

Ah, thanks--I didn't know about that command! I was considering using
"git status --porcelain", but ls-files looks exactly like what I want.

The more I think about it the more I think you're right that it should
respect .gitignore on the default case and have another option to be
really thorough (even if my build system isn't always fragile, it's
sometimes nice to be overly cautious just for my own paranoid peace of
mind).
Perhaps --clean (or --untracked) respects .gitignore and --all just flat
out does everything?

They do in indeed, but you're right, that would be a good automated test
to add.
Thanks, I greatly appreciate the help.
