c-post-command

[martin rudalics <rudalics@gmx.at>]

After setting the major mode of a buffer to 'c-mode' and switching to a
buffer in 'text-mode', the value of 'post-command-hook' in that buffer
includes 'c-post-command'.  I suppose this comes from

   (add-hook 'post-command-hook 'c-post-command)

in 'c-basic-common-init' which is removed via

   (remove-hook 'post-command-hook 'c-post-command)

in 'change-major-mode-hook' that calls 'c-leave-cc-mode-mode'.  But such
"removals" happen only when changing the major mode of a buffer and not
when simply switching buffers.  Even if 'c-post-command' returns
immediately when not in a 'c-mode' buffer, it is disconcerting to see
that function in ‘post-command-hook’ when working in some other mode.

Is there any reason not to use

   (add-hook 'post-command-hook 'c-post-command nil t)

in 'c-basic-common-init'?

As an aside, 'c-leave-cc-mode-mode' also does

   (remove-hook 'post-gc-hook 'c-post-gc-hook)))

which I see nowhere added before.
