Thank you.

I have replaced all occurences of info with val and nuked the declaration
of info as the GETCAPS switch was the only place it was used .... it's
working now :)

The interactive performance seems to have improved somewhat in 2.1.80 but
I haven't been running it long enough to judge for certain ... 2.1.79
seemed to thrash a bit and skyrocket the load when opening largish folders
in pine. Everything else turned to chewing gum in 2.1.79 but it seems
better in 2.1.80.

Anyone care to comment on this?
