SUBJECT: Bug in asciitopgm from libgr-2.0.13 (with patch)

asciitopgm can dump core (or do other nasty things) when an input line
is longer than expected.  This seems to have been noticed but not
addressed by the code's author(s); a comment reads

	* NOTE that we assume the user specified a sufficiently large width!

Anyway, this crash happens because the line

	obuf[i++] += gmap[c];

in the switch's default case doesn't ensure that i < cols.  My
suggested patch simply ensures that i < cols before executing that
statement.  (Arguably, it should also give a warning.)
