I'm ambivalent about the messages, but FWIW I think you did the right
here: it is simpler to approve a patch that doesn't change messages than
it is to approve one that does.

I'd prefer we not introduce new globals unless truly necessary.

A from_tty global would be fine for things strictly related to the CLI,
I suppose (the difficulty being enforcing such a rule), but for the core
I think parameterization is better.

Jan> SOLIB_CREATE_INFERIOR_HOOK was not modified as its only called

It would be nice to nuke SOLIB_CREATE_INFERIOR_HOOK, given that there is
just a single definition.

Ok.
