These functions are as important for programmers as is `custom-theme-p'.
It is especially important to distinguish them, in particular wrt
`custom-theme-p', which uses only `custom-known-themes'. An "available"
theme is not necessarily a "known" theme. This can be confusing.
For example, I was doing this at first:
(defcustom doremi-custom-themes ()
"*List of custom themes to cycle through using `doremi-custom-themes+'."
:type '(repeat (restricted-sexp :match-alternatives (custom-theme-p)))
:group 'doremi-misc-commands)
But what I really needed was the following, because the "available" themes
are not necessarily available from the outset - the set of "known" themes
is too limited for use here.
(defcustom doremi-custom-themes ()
"*List of custom themes to cycle through using `doremi-custom-themes+'."
:type '(repeat (restricted-sexp
:match-alternatives
((lambda (s) (memq s (custom-available-themes))))))
:group 'doremi-misc-commands)
