[gentoo-portage-dev] [PATCH] Ignore some unowned files during collision check

[Krzysztof Pawlik]

Hello,

I've added a new variable to portage named
COLLISION_UNOWNED_IGNORE_PATTERNS. It works similar to COLLISION_IGNORE, it
specifies shell patterns for unowned files that can be overwritten (will not
cause collision-protect or protect-owned to go off).

I'm not convinced about the name - if anyone has better idea I'd be more than
happy to change it :)

Attached patch adds code to vartree, documents new variable in manual page and
adds a default to make.globals.
