Bug#677608: Option --git-pristine-tar fails if package version contains the "~" sign

[Mike Gabriel]

Package: git-buildpackage
Version: 0.5.10
Severity: minor
Tags: upstream

Hi Guido,

while packaging kiwix we stumbled over an issue with the --git-pristine-tar option.

The package version currently is 0.9~beta6.3-1.

git-import-orig works fine with that version (tarball is 0.9~beta6.3). The 
import tag on the upstream branch gets named upstream/0.9_beta6.3.

On git-buildpackage -uc -us the orig tarball gets created from 
upstream/0.9_beta6.3 alright (as kiwix_0.9~beta6.3.orig.tar.gz).

However, if I use git-buildpackage -uc -us --git-pristine-tar, I get the following
error:
