Re: Vim under screen screwing up console on close

[Aaron Humphrey <alfvaen at gmail dot com>]

Looks like vim isn't the only problem here, nor is screen.  I was able
to see some other poor behaviour by looking at a man page and then
searching for a string which didn't exist--whether running 'screen' or
not.  It displayed "Pattern not found" on the bottom line, which
caused a bunch of lines to be pushed upward by one, leaving much
duplication and confusion.  (I would attach a screenshot here, but the
mailer-daemon rejected both png and jpg formats.  What does it like,
gif?  bmp?  tiff?)  I believe I'm using 'less' for my pager, and I can
see the same thing using less.  Less, vim, man...wasn't there another
issue recently that involved those?  Maybe I'll try that snapshot and
see if that helps with this problem at all.
