	instead of the interactive goto-line.  Written as suggested in
	the comment to the latter.  All uses changed.

2025-05-05  Stefan Monnier  <monnier@iro.umontreal.ca>

	elisp/cflow-mode.el (cflow-font-lock-keywords): Minor tweaks
	Don't rely on `\S` and `\s` which depend on syntax tables and
	rarely do
	what we want with newlines.  More specifically, this fixes
	mis-highlighting the whole of `NN]\nfoo_bar ()` as a function
	because \n is matched by `\S` (because the syntax table says \n is
	a comment-ender rather than a space).
	Recognize `(R)` even if it's followed by `[see NNN]`.
	Highlight the `[see NNN]` as well.
	Change regexp which used `+-|` so that it matches those 3
	chars rather
	than all chars from ASCII 43 (+) to ASCII 124 (|).
