I do not think we want to add more, but use of skip_prefix does
sound sensible. I was very tempted to suggest
static const char *scissors[] = {
">8", "8<", ">%", "%<",
NULL,
};
const char **s;
for (s = scissors; *s; s++)
if (skip_prefix, c, *s, &end) {
in_perforation = 1;
...
break;
}
}
if (!s)
... we are not looking at any of the scissors[] ...
but that would encourage adding more random entries to the array,
which we would want to avoid in order to help reduce the cognirive
load of end-users.
In hindsight, addition of an undocumented '%' was already a mistake.
I wonder how widely it is in use (yes, I am tempted to deprecate and
remove these two to match the code to the docs).
