I worked on this idea; see this revision

http://goffredo-baroncelli.homelinux.net/bazaar-dev/bazaar-webserve-dev?cmd=revision;revid=ghigo%40venice-20060903172053-e6343fedd1812cd4


If I add in the config file the option "commentfilter" I am able to replace 
the text in the comment. For example in my test I added the following rule ( 
one line )

commentfilter = replace:@bugid:([0-9]*)@<a 
href=http://bugzilla/bugid=\1>bugid:\1</a>@;;replace:@test:([0-9]*)@<a 
href=http://bugzilla/test=\1>test:\1</a>@

So every occurence of bugid:XYZ is replaced with a URL pointing to

 http://bugzilla/bugid=XYZ

And every occurence of test:XYZ is replaced with a URL pointing to

 http://bugzilla/test=XYZ


Every rule is separed by a ";;"; the syntax is :

<command>:<parameters>

For now only the command "replace" is implemented. For the command "replace:" 
the syntax of <parameters> is

<separator><reg-ex><separator><replace-string><separator>

where

<separator> is a arbitrary character ( '@' in my examples )
<reg-ex>    is a regular expression that is used to select the string that
            will be replaced
<replace-string> is the string that will be inserted

Comments are welcome.
