Matt Wozniski f8019878d0 Don't run CSApproxImpl unless t_Co is sane.
This was set up to allow CSApproxImpl() to run if either t_Co was set to
88 or 256, or if we were running in gui vim.  Presumably this was added
for CSApproxSnapshot, but that sets t_Co to something sane even in gvim.
This was causing errors slightly later when t_Co was unset.
