	r0 (2025-07-03; n3670):
	-  Initial draft.

Rationale
	Programmers keep struggling to understand what strpbrk(3) does.
	<https://github.com/shadow-maint/shadow/pull/1158#issuecomment-2566663723>

	Plan9 defines it as strchrs(), which is the name this API should
	have gotten in the first place.  That way, it's obvious that
	it's like strchr(3), but that it checks for several characters
	(thus, the plural).

	Since existing code depends on strpbrk(3), let's keep it there
	as an obsolescent equivalent function.

Proposed wording
	## TODO
