	Templates for VIM
	by Phillip Berndt, www.pberndt.com

	
	Phillip Berndt, Sat Apr 14 22:20:31 CEST 2007:
		Nihil (nihil <at> jabber.ccc.de) reported some problems in his
		VIM environment, which inserts a CR after the first character
		in templates. He came up with a workaround. Replace the
		imap command in the end with
			command('imap <unique> ^D ^[:py template_complete()<CR>a')
		to make it work.
