-#     Revision 1.27  2006/10/08 17:00:51  fabiankeil
-#     Modified webbugs filter to create a comment around the offending
-#     image instead of removing it entirely.
-#
-#     Adjusted regex to only match if there's at least one whitespace
-#     before the width and height attributes. Makes it more likely that
-#     they are indeed attributes, and not part of the value of another attribute.
-#     Solves BR 1035587.
