Some customize options use key :value-to-internal with customize type
"repeat". One example is variable message-ignored-news-headers in
lisp/gnus/message.el:
(defcustom message-ignored-news-headers
"^NNTP-Posting-Host:\\|^Xref:\\|^[BGF]cc:\\|^Resent-Fcc: [...]
"*Regexp of headers to be removed unconditionally before posting."
:group 'message-news
:group 'message-headers
:link '(custom-manual "(message)Message Headers")
:type '(repeat :value-to-internal (lambda (widget value)
(custom-split-regexp-maybe value))
:match (lambda (widget value)
(or (stringp value)
(widget-editable-list-match widget value)))
regexp))
(I cut one long line and added ellipsis "[...]".)
:value-to-internal key doesn't seem to be documented anywhere so I
consider this a documentation bug. Please add a description for the key
- perhaps to the info node "(elisp) Type Keywords" - because it seems
very useful for Emacs extension writers.
