* bug#39190: 28.0.50; two buffers with same buffer-file-name (diff-syntax-fontify-props)

If I read correctly, diff-syntax-fontify-props sets buffer-file-name of
a temporary buffer to an existing one.  This is not necessarily a bug,
but it definitely looks strange that we have two buffers with different
contents and the same buffer-file-name.

Eglot (in ELPA) runs into problems because of this
(https://github.com/joaotavora/eglot/pull/233).

Is there a recommended way to check in an after-change-major-mode-hook
whether the current buffer is or isn't a temporary diff buffer?  For
example, to check if first character of buffer-name is space.

Thank you.
