Description Joel 2013-11-05 22:45:32 UTC 
show-installed -f yum
outputs the options in the wrong format.  It outputs groups and exclusions as:

@cinnamon-desktop -eog

While this matches the documention in yum manpage, it doesn't match the actual program: https://bugzilla.redhat.com/show_bug.cgi?id=1026598

What is needed is either "--exclude=eog" or a "-- -eog".

Thanks!

We can add '--' at the beginning, but there's a problem that end-of-options is recognized only once. It's likely that most users that feed show-installed output to yum *already* use something like "yum <options> install -- $(cat show-installed-output)", and the following patch would break that:

--- a/show-installed.py
+++ b/show-installed.py

         else:

To avoid that, I'd rather not touch the code, and suggest using "--" when using the "--format yum" option.
