Problem: The ``vimtutor'' command creates the temporary copy of the Vim
Tutorial in a complicated and potentially insecure way.
Solution: Use Vim builtin function tempname() to find the temporary file name
Please NOTE: It is unclear this is in fact exploitable anywhere
Please NOTE: The patched VMS script has not been tested.
It also fixes the following error:
Error detected while processing /usr/local/share/vim/vim72b/tutor/tutor.vim:
line 163:
E486: Pattern not found: ext .= '.utf-8'
