As a user, when I get an email that says
> Alice edited the task description
I usually want to see //what// the change was. It's currently a complete mystery, that requires me to:
# open the page in a browser,
# scroll down to the line where the edit was made
# click on "(`Show details`)"
There are 3 possible ways to solve this. In the email notification:
* Provide a direct link to the diff, e.g. https://phabricator.wikimedia.org/transactions/detail/PHID-XACT-TASK-ziuazd55shmmdl7/ (which should also link back to the task it is associated with)
* or, Provide a link to the specific timestamp (to remove the need to scroll to it), e.g. https://phabricator.wikimedia.org/T75851#1139254
* or, Provide the diff itself in the mail. -- [this option is possibly too complicated (HTML vs plaintext, etc) but possibly a worthwhile long-term goal?]
Thank you! :-)
