Backport StripTrailingWhitespace to pre-for Vim
Use a slightly more verbose but more compatible `:while` loop to
accommodate very old versions of Vim that do not have `:for`.
Vim 6.2 gives the following terminal output when the `:for` version is
run:
Error detected while processing /home/tom/.vim/config/whitespace.vim:
line 13:
E193: :endfunction not inside a function
However, it accepts this new version with no complaint, and the function
seems to work properly.
