commit ea010d85e796dc979cdfacc91bc1d06a8c6dac7c
Author: David Lutterkort <lutter@redhat.com>
Date: Fri Apr 29 14:32:13 2011 -0700
path expressions: allow whitespace inside names
This makes the path expression '/files/etc/foo bar/baz' legal, i.e. it is
no longer necessary to escape whitespace in path expressions.
Fixes BZ 700608
