Buffer size calculation breaks when `header-line-format` is set

[ft]

I'm setting header-line-format by default, which is undesirable with which-key-mode. I'm currently fixing this manually in a which-key-init-buffer-hook, but I suppose it would be useful for this to be fixed for other people too. The following does that.

Subject: [PATCH] Unset header-line-format format in " *which-key*" buffer

Similarly to mode-line-format, header-line-format just takes up space and
currently also breaks window size calculations for the buffer. This sets
it to nil in order to suppress its display.
