bug#57321: 29.0.50; doc string and customization form for variable auto-save-file-name-transforms suboptimal

[Gregor Zattler]

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
