`pkg_info -Q` fails with branch name

[Yuichiro NAITO]

I've tried to search python 2.7 package with a branch name.
`pkg_info -Q` fails with following message.
$ pkg_info -a -Q python%2.7
Can't locate object method "match" via package 
"OpenBSD::Search::FilterLocation" at 
/usr/libdata/perl5/OpenBSD/Search.pm line 27.

It seems that FilterLocation class doesn't have 'match' method.

I assume that a branch name can be used as same as `pkg_add python%2.7`.
`pkg_add python%2.7` succeeds to install python-2.7 package.
