Would be nice if jinja2 makes use of the 'vim-syntax' USE flag and adds 'jinja.vim' and 'htmljinja.vim' from: http://www.vim.org/scripts/script.php?script_id=1856
These files are included into upstream tarball now, so here's small patch for ebuild to install them
Created attachment 261416 [details, diff] Patch to install vim syntax files for dev-python/jinja
Fixed in dev-python/jinja-2.5.5.
