We currently use email notifications to see what changes are made to issues we're assigned. We usually don't have to open Redmine to see the changes, because the email contains (almost) all of them listed inline:

• Category changed from Foo to Bar
• Status Changed from New to Resolved
• etc.

The only attribute that doesn't not have a diff listed inline is "Description". The email has a generic/static "Description updated" line for it.

In order for us to actually see the diff for Description, we have to open the issue in Redmine and then click the "diff" link ("example diff":http://www.redmine.org/journals/diff/73087?detail_id=56862 from a random issue #23717)

Couldn't the 'Description diff' already be shown in the email inline, so we are no longer forced to open Redmine only for the diff? Descriptions are updated quite frequently in our workplace, so it would really help us.

A similar issue was listed before, but for wiki page changes (#12508, #11530). I'm not sure if the hook approach taken there is the best one for this or a different approach might work better.
