Description of problem:

The bugzilla seems to mark "bug\s+\d+" as a link to bug within bugzilla. This
should probably be changed to something like "bug +\d+", to prevent the link
from appearing when there is a newline, which seems to denote that the word bug
is not related to the number following on the next line.

Version-Release number of selected component (if applicable):

Current (2.18)

How reproducible:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=202653

Steps to Reproduce:
1. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=202653
2. observe the "Steps to Reproduce"
  
Actual results:

The word "bug" and the number "2" are a link to
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=2, because of the following
HTML code:

this <span class="bz_closed"><a href="show_bug.cgi?id=2" title="CLOSED FIXED -
broken links of default index.html">bug
2</a></span>. run

Expected results:

There should be not link there.
