Subject: Fix write_gitignore for git version >= 2.7
X-Git-Url: https://git.madduck.net/code/vcsh.git/commitdiff_plain/a82dfd998413a033234b6e604200331e64f8528f?ds=inline;hp=--cc

Fix write_gitignore for git version >= 2.7

As of git version 2.7 it is no longer necessary to include parent
directories in the list of files not to be ignored.

This fixes #195.
