Dear Emacs developers,
(customize-variable 'auto-save-file-name-transforms)
shows the customization form for this variable accompanied
by a doc string.
According to the doc string the argument UNIQUIFY may have
on of more than two values but the form only gives access to
a toggle switch.
Instead there should be a value menu, IMHO.
The documentation for UNIQUIFY, does not state clearly what
happens if UNIQUIFY is nil and what the perils are.
Where the doc now says "is non-nil" it probably should say
"is t" instead.
Thanks for your attention, Gregor

I'm unable to reproduce this -- with "emacs -Q" in Emacs 29, I get:

Well, it doesn't make the names unique, so you could overwrite
a different autosave file, but does that need to be said?

No, all non-nil values (except the ones in secure-hash-algorithms) work
fine.

You get, what I got.
What I meant was, that one can only toggle the value of
UNIQUIFY from on to off and back, while this argument also
allows for the names of some secure hashes. Therefore for
the sake of completeness the customization form should
feature a value menu instead of a toggle switch.

The doc string is upside down. Only after reading the
last part about the secure hashes one knows that "non-nil"
actually means "non-nil except for the names of secure
hashes".
Only when reading the part regarding UNIQUIFY being
"non-nil" one understands that the talk before about
replacing within the regex match actually is about the
directory the auto-saved-files are stored under.
That might not be important, though. I can easily live
without the doc string being changed, now that I groked it.
Ciao,

Ah, sorry -- I misunderstood. I've now fixed the UNIQUIFY defcustom
type.

Yes, true. I've now rephrased it in Emacs 29.
