Subject: [PATCH] man(1): Fix override dir handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Previously, override dir was affecting only some cases
of manpath determination.
Apply it only when all paths has been gathered instead.
(Depending on the definition of when the override dir applies,
this might not be correct).
Also look for override dir when sorting candidates.
Fixes src/tests/man-9 failing when --with-override-dir=od
is passed to ./configure.
