bug#4837: with-fewer-warnings ?

[Glenn Morris]

Severity: wishlist

`with-no-warnings' suppresses all compilation warnings.

I would like to add `with-fewer-warnings' (or some similar name) that
suppresses only some warnings.

Eg (with-fewer-warnings '(obsolete cl-functions) ...)

would not warn about obsolete things or cl-functions in the body. The
possible arguments are the members of byte-compile-warnings.

I can implement this if it is considered worth it (it's very similar
to with-no-warnings).
