patch 8.0.0649: when opening a help file the filetype is set several times commit https://github.com/vim/vim/commit/9049298f8d0bbc237b7c666c7ad6cdabe738e8fc Author: Bram Moolenaar <Bram@vim.org> Date: Thu Jun 22 14:16:31 2017 +0200 patch 8.0.0649: when opening a help file the filetype is set several times Problem: When opening a help file the filetype is set several times. Solution: When setting the filetype to the same value from a modeline, don't trigger FileType autocommands. Don't set the filetype to "help" when it's already set correctly.

" Vim script to cleanup a .po file:
" - Remove line numbers (avoids that diffs are messy).
" - Comment-out fuzzy and empty messages.
" - Make sure there is a space before the string (required for Solaris).
" Requires Vim 6.0 or later (because of multi-line search patterns).

" Disable diff mode, because it makes this very slow
