When reading in from the modeline in buffer.c, mg uses a pointer
called bufp pointing to a buffer called bufn. It would seem to make
sense to use bufp in any further processing. These functions don't:
switch-to-buffer-other-window (poptobuffer())
kill-buffer (killbuffer_cmd())
insert-buffer (bufferinsert())
This diff changes the above three instances to use bufp instead of
bufn once eread() has been used. No functional change intended.
ok?
