Subject: [PATCH] gnu: maxflow: Correct version to 3.0.5.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This won't be picked up by ‘guix package -u’, but the code is identical
anyway.  By changing this now, fewer installations will fail to upgrade
at all if upstream ever release a new <3.4.

* gnu/packages/maths.scm (maxflow)[version]: Change to 3.0.5.
[source]: Use version tag instead of raw matching commit.
