bug#65195: 13.2.1; (La)TeX-fold-math-spec-list have the wrong custom type

[Tony Zorman]

Hi,

the custom type for `(La)TeX-fold-math-spec-list' is

  (repeat (group (choice (string :tag "Display String")
                         (integer :tag "Number of argument" :value 1))
                 (repeat :tag "Math Macros" (string))))

However, the following is a perfectly valid definition

  (setopt TeX-fold-math-spec-list
          `((,(lambda (word) word) ("mathbf"))))

(the code to handle functions is in `TeX-fold-hide-item').

Currently, the `setopt' macro throws some warning, because a function is
not part of the type (presumably this was forgotten). I propose to have
a type closer to what `TeX-fold-macro-spec-list' has:

  (repeat (group (choice (string :tag "Display String")
                         (integer :tag "Number of argument" :value 1)
                         (function :tag "Function to execute"))
                 (repeat :tag "Math Macros" (string))))

The relevant functions called, like `TeX-fold-make-overlay' would also
have to have their documentation adjusted.

I can prepare a small patch, or someone can commit this directly,
whatever people feel like is easier.

Thanks,
   Tony
