[OE-core] Commit messages becoming too short

[Richard Purdie]

There appears to be a general trend towards short commit messages. I
don't impose a "must have a long log and short log" policy but I'll have
to if things don't improve.

To be clear, the commit message needs to say not just what changed but
*why* the change is necessary, e.g. what error it causes without it.

Commit messages need to stand alone without reference to any linked
bugzilla entry either, that is just there as a way to further look at
the issue.

I'm going to be getting stricter about this.

Cheers,

Richard
