+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.
+

+The man-db package includes five tools for browsing man-pages:

+manual page names and descriptions. manpath determines search path
+for manual pages. lexgrog directly reads header information in
+manual pages.
