Subject: [PATCH] Remove chop().

In curses_log() we currently we call chop(), which calls strlen()
to find the last character of the given string. This is unnecessary
since xvasprintf() returns this information anyway, we just have to
remember it.

With this change the last user of chop() is gone, so this patch
removes chop() from string.c.
