I spoke here of "loading", not "finding" the library.
Sorry, that was a mistake.  (And `find-library', unlike
`load-library', which I was thinking of there, didn't
exist in 1985.)

But it points out precisely the problem.  `load-library'
does NOT have this regression.  Your argument about the
library being only "mouse" clearly doesn't apply for
`load-library': you can do `M-x load-library mouse. TAB'
and you get the expected completions.

`find-library' should behave the same way, as it always
has, before this regression.  Please reconsider.  Thx.
