Subject: Instead of "cd .." hackery, find the path of ./all by looking at $0.
X-Git-Tag: xonotic-v0.8.2~18
X-Git-Url: https://git.xonotic.org/?a=commitdiff_plain;h=7cce522db16998cca1d914d6b81bb6e2de3a5240;p=xonotic%2Fxonotic.git

Instead of "cd .." hackery, find the path of ./all by looking at $0.

This only supports invoking ./all directly (not via $PATH or symlinks),
but should already be a lot better than before.
