I agree. Usually when using vim tabstop should not be changed, only
shiftwidth. I am not sure if using softtabstop is "compatible" with
other editors. Most other editors are not able to make a difference
between tabs at indentation level and somewhere else in the file. This
could be the reason why our default modeline is changing tabstop.

Useless if not also using foldenable. I would leave this for everyone to
add in their .vim/filetype.vim. Some people do not like folding.

For example:
  au BufRead,BufNewFile Portfile setlocal foldenable foldmethod=marker

I have that set for all text/code files anyway. I don't think we should
enforce a specific textwidth for Portfiles. For example commands in
destroot phases or variant lines with descriptions are often longer than
80 characters.
