bug#22019: 25.0.50; Bad comment in `character-fold-to-regexp'

[Drew Adams]

This part of an explanatory comment is inadequate and inappropriate:

 ;; See commit message for a longer description.

What commit message?  The source code should contain the description.
If a VC commit message happens to also contain the description, so
much the better for it.  But that doesn't help a reader of the code.

This comment is intended to make clear what the design/intention is.
Readers of the source code deserve the additional design information
as much as maintainers who might bother to access the relevant commit.
