[StGit PATCH] Add import -p option

[StGit PATCH] Add import -p option

[Catalin Marinas]

This patch renames some of the existing import options and adds the -p
(--strip) option which allows stripping the leading slashes of the diff
paths.

Looks good (and the intent is very good). The import test should
probably be augmented with a test case for -pN, though. (And since you
didn't have to change the test in this patch, presumably the two
options you renamed weren't tested either.)

This test should probably be "if strip != None". It doesn't _really_
matter, technically, since -p0 is the default, but still ...

Yes. I'll try to add one. As you noticed, not all options are tested.

I modified it after posting the patch. The git default is -p1, so we
would miss the -p0 case.

Ah ha! Sometimes it actually does pay to be pedantic ...
