A fixes tag is not the same as a stable tag, I really want to see Fixes
tags on patches which are bug fixes as it makes it simple to see the
context in which a bug was introduced.

vs. the stable tag: scary warnings tend to confuse users and cause people
to send bug reports. So in this case I'd add one.
