Details:

In scrollback mode, vi-style search commands sometimes fail to find text on
long wrapped lines.  For example, if you have an 80-column window, and you run
this:

    perl -e 'print "X" x 77, "foobar\n"'

It should print a long line that wraps in the middle of the word "foobar".  If
you then enter scrollback mode and use the ? or / commands to search for
"foobar", though, screen won't find it!  (It works if you do an emacs-style
search with C-s or C-r, but emacs-style search is weird in a different way: it
actually ignores *all* line breaks, not just the ones caused by line
wrapping.)

I've attached a patch to fix vi-style search.  With this patch, it correctly
finds text on long lines regardless of where they happen to wrap.
