[Quilt-dev] [PATCH] setup: Fix a corner case in create_symlink

[Jean Delvare]

When a link's target is the directory it lives in, create_symlink
would erroneously link to "..". Fix the code to properly link to "."
instead.

This fixes openSUSE bug #916007:
https://bugzilla.opensuse.org/show_bug.cgi?id=916007

Credits to Robert Milasan for spotting the bug.
