[maint/rfc] Add Obvious Fix Rule

[Andrew Cagney]

Comments (on the grammar)?  Stan Shebs posted a suggestion leading to
this some time ago and no one objected to the theory :-)

			The Obvious Fix Rule

All maintainers listed in this file are allowed to check in obvious
fixes.

An "obvious fix" means that there is no possibility that anyone will
disagree with the change.  Something like bypassing an interface will
result in instantaneous and loud complaints.

A good mental test is "will the person who hates my work the most be
able to find fault with the change" - if so, then it's not obvious and
needs to be posted first. :-)
