It's actually a bit worse than that. Because the windows shell doesn't
expand globs, but *does* expand quotations, we don't have a way to tell
if something is quoted. For example:

bzr ignore *
bzr ignore "*"

In both cases we will get:

sys.argv == ['bzr', 'ignore', '*']

And that means that we will have no way to tell that the user really
meant to supply a pattern versus they really meant to expand the glob.

So we default to one way or the other based on what is the most likely
use case. (add * is expanded, ignore * is not.)

The only thing we *could* do is to look at single quoted strings, since
Windows doesn't do anything with them. For example:

bzr ignore 'foo bar'
becomes

sys.argv = ["bzr", "ignore", "'foo", "bar'"]


Of course, that would then assume that people never use apostrophe's in
their filenames.

Anyway it is generally an ugly mess, and you are far better off figuring
out a good GUI for it. :)
