1) (MAJOR) The old/new values in the audit log are truncated. Where the change happened later in the string (as per the screen shot), it is IMPOSSIBLE to tell what changed.

Desired: always display all the text, perhaps with inner scrollbars.

2) The CSS styles for the old/new value are different. The Old wraps, the New truncates, and you have to scroll all the way to the bottom of the page to use the horizontal scrollbar for that DIV.

3) (Stretch) steal the diff code that JIRA uses in it's emails to highlight the differences between the Old and New values.
