Gnus/5.110011 (No Gnus v0.11) Emacs/23.1 (gnu/linux) |
In a docstring has an info link with a newline in it like
(defun foo ()
"Foo.
Info node `(emacs)File
Variables'."
nil)
The link is buttonized by M-x describe-function, but pressing Ret on the
button gets an error
No such node or anchor: File
The end of `gnus-level-unsubscribed' is an example of this -- though it
has a separate problem of needing the manual name `(gnus)Group Levels'.

* help-mode.el (help-make-xrefs): For info node links turn
newlines into spaces. Link node names with newlines are matched
by help-xref-info-regexp and buttonized, this change ensures they
can be followed successfully with Ret.
