I'm not so sure how I feel about this one. To change this in essence requires us to allow HTML input in the title and description fields and implement a filter that matches GitHub so we aren't opening ourselves up to a hack.

as for description it works ok with commenting like <br> but not for title see: http://issues.joomla.org/tracker/jtests/82 (try to use esting <br>)

if someone what us to hack this days he needs to open a issue on github with the code into the title this gets synced without cleaning into JTracker. Only on saving the issue it gets cleaned.

Did we have a chance to handel it by only removing the <...>? I'm not sure for the security impact.

But so we have all data there ;) If someone realy need full HTML Codes they should use commeting like <your very bad html or other code> into the description

Description works fine because it doesn't filter data (we may be able to put the HTML filter around that, not so sure what side effects it could cause); the title is filtered as a string through the filter package. As for the hooks they probably need to be refactored to store through the IssueModel versus IssueTable object as the model is doing all the filtering.

So #639 should fix it?

Well, partially. Now both sides should be using the same rules. But, HTML is getting stripped in the title for both elements now. So, we may need to use the HTML filter in Joomla's InputFilter object to make things work.
