[mkgmap-dev] Commit: r980: Fix explicit setting of mapname when the file name is numeric.

Version 980 was commited by steve on 2009-03-15 22:01:57 +0000 (Sun, 15 Mar 2009) Fix explicit setting of mapname when the file name is numeric. Numeric filename set the mapname from the filename, unless a mapname argument is given. In that case all mapnames after that are determined by the set value and not by the filename.
