Re: [RFA] Rework symbol searches to move Ada-specific stuff to ada-lang.c.

FWIW, Paul actually knows a lot more about the ada-* code since he wrote
most of it. So I do not feel that it needs to be approved by me before
he can commit Ada-related changes.  But a second pair of eyes never hurts,

I don't oppose this change, but I really don't understand why that's
something we should avoid.  If it's something Ada-specific, why not
saying so in the function name?

A formatting nit: Doug would like us to add an empty line after the
comment that documents a function...

Same here.

Same here.
