mrxvt Code

Some changes for column<->width problematic

Segfault fix (Patch due to dale@...).

Steps to reproduce:

1. Generate more than "Mrxvt.saveLines" lines of output (eg, "for ((i=0; i
<30000; i=i+1)); do echo $i; done")
2. Scroll all the way back up to the top (shift+PgUp) and LEFT-click once.
3. Press up arrow and hit Enter (ie, repeat step 1).
4. Scroll all the way back up to the top (shift+PgUp) and RIGHT-click once.
5. When running with -cf /dev/null, then step 4 usually did not cause a seg
fault on the first try. So I would LEFT-click once and then repeat steps
3-4.

The seg fault usually happens after doing this a few times.
