[pacman-dev] [patch] Fix -Qii support and output, some refactoring

Dan McGee dpmcgee at gmail.com
Sun Jan 7 21:33:13 EST 2007


Libification added a regression on multiple 'i' support for a query;
this option allows additional information to be printed about the
backup files. While fixing, noticed the previous hack-up with SHA1
addition didn't work as expected because it had probably never been
tested, so also refactored this whole section into a new function and
fixed existing problems. Finally, a few formatting changes in pacman.c
for clarity.
