Thanks for confirming!

Seeing as nobody seemed to notice or care that this use case was broken
for three years and two major releases, I’m personally inclined to
proceed further in the direction Lars set previously by considering
Occur and Grep as proper special modes, with special C-x C-q behavior,
like Dired.  I don’t find the rationale particularly compelling that
Occur and Grep buffer contents are more commonly edited as raw text than
Dired.  Not enough to justify the discrepancy, anyway.  With
special-mode’s bindings in mind, I think it makes more sense to change
modes before editing the contents.

I might have to retract that comment about prescribing workflows.  This
series is tweaking defaults, so I guess that’s its whole purpose!  Maybe
others can chime in on their tastes here as well?

Thanks for your input!
