I was about to suggest this function can be simplified and maybe
even inlined by the use of strspn or strcspn, but I think manual
processing of the string is fine, too, as it would not really be shorter.
Hmm, I fear that iterating over a line one-byte-at-a-time and
running strchr(separators, *c) on it for each byte has a performance
implication over running a single call to strcspn(line, separators).
If we do that, there is also the necessity of creating a string that
combines the separators and '=' (I guess '\n' is not necessary now,
since all the lines are null terminated). I'm OK either way.
(We could cache that string, although I would think that if we did that,
we might as well write the loop manually, like in this patch.)
