I'm trying to configure a phabricator instance, and I find that change the arcanist default template when we use arc diff can be very useful for the team.
Actually the template contains this text:
```
<<Replace this line with your Revision Title>>
Summary:
Test Plan:
Reviewers:
Subscribers:
# Tip: Write "Fixes T123" in your summary to automatically close the
# corresponding task when this change lands.
# NEW DIFFERENTIAL REVISION
# Describe the changes in this new revision.
#
# arc could not identify any existing revision in your working copy.
# If you intended to update an existing revision, use:
#
# $ arc diff --update <revision>
```
I'm googling to find any way to change this default template, but I can't find it...
There is any way to "personalize" this template?
