Reduce Subject length from GitHub

[Milamber]

Hello,

Probably that is a Infra task, but before I would like ask to you, if 
that would be better if the prefix of subject could be reduce to allow 
to see the main subject of a mail send by Github ?

See this screen shot from my SeaMonkey (mail client), the prefix is the 
only visible text.

A new prefix like "[GH] CS PR: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" seems 
better ?
(currently: "[GitHub] cloudstack pull request: CLOUDSTACK-8991 ...")

Any thoughts?
