I agree that this would be more accurate, but isn=E2=80=99t there also a ri=
sk
with making hints too long?  I=E2=80=99m split between the idea of providing
concise hints that can be pasted and get things done, and the idea or
not trying to be a substitute for the manual.

Actually, I was also wondering whether we should provide a configurable
mechanism that would, by default, automatically delete old GC roots and
maybe even run the GC automatically when needed=E2=80=94similar to what Git
does.

Thoughts?
