I'm also attaching the code patch, in case you have some comments about the option and its help documentation itself. 2009-06-23 Joel Brobecker * gdb.texinfo (Other Misc Settings): New node. I tried to find a good place for it, but nothing really seemed appropriate. Peharps if we renamed the "Screen Size" section to be a little more generic, we could put our new option there. But it seemed a little artificial, and might make finding these screen-size related option a little harder to find. Since the latter will probably be much more widely used, I didn't think it was the best thing to do. Hence the new "misc" section. OK to apply?
