[Nasal-cvs] gtklib.c

[Andy Ross]

Update of /home/nasal-cvs/nasal/src
In directory purr:/tmp/cvs-serv29089

Modified Files:
	gtklib.c 
Log Message:
Fix some overflow conditions in the double-stepping argument parsers.
If we're doing i+=2 in the update, we need to test for i<argc-1, not
just i<argc.  Also clean up some trailing spaces; sorry for the
whitespace diffs.
