[pacman-dev] CVS update of pacman-lib/src/pacman (query.c)

[Aaron Griffin]

    Date: Thursday, March 22, 2007 @ 03:32:54
  Author: aaron
    Path: /home/cvs-pacman/pacman-lib/src/pacman

Modified: query.c (1.31 -> 1.32)

* -Qo now properly resolves paths when finding an owner
  NOTE that we do NOT want symlinked *files* resolved, only paths (i.e.
  /usr/lib/perl5/site_perl/*)
