Subject: Fix use_reduce() so that it appropriately raises an InvalidDependString
X-Git-Tag: v2.1.5.3~56
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5e39470e1d14bf9cca26bc955354f409ddd8b2d4;p=portage.git

Fix use_reduce() so that it appropriately raises an InvalidDependString
instead of an IndexError in some cases (avoid IndexError by using slice
notation). (trunk r10391)
