The Customize buffer is supposed to be a user-friendly, easy interface
to use, and displaying types like

(alist :key-type symbol :value-type (choice symbol integer))

which only would make sense to a programmer would be the wrong way to go
here.  The Customize interface already tries to guide the users as much
as the type spec allows.

I'm sure there are individual doc strings that could stand improving,
though, in which case bug reports for those would be welcome.  But I'm
closing this bug report.
