Subject: Fix use_reduce() so that it appropriately raises an InvalidDependString
X-Git-Tag: v2.2_pre8~123
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=7502324ea6d85f96b251973014684cba5251d973;p=portage.git

instead of an IndexError in some cases (avoid IndexError by using slice
notation).
