[PATCH] Support displaying function name in the header line |

Tags: patch
In some languages, the function name as displayed in the mode-line by
which-func-mode can be quite long. It's useful to be able to display
it in the header-line instead. Let's support that.
This was my original motivation for Bug#63825, so that the header line
was not displayed when which-func-mode wasn't enabled, but just teaching
which-function-mode to handle this is much easier.
* lisp/progmodes/which-func.el (which-func-use-header-line)
(which-func-use-mode-line): Add.
(which-func-try-to-enable): Support which-func-use-header-line.
(which-func--disable): Add, to support which-func-use-header-line.
(which-func-ff-hook, which-func-update-1): Use which-func--disable.
