Ah.
We could change the retval of the function to true/false and use the
ascii_toupper() and IS_ASCII_WS() function in your loop above. Or keep
the comparison and just do something like:
size_t a_len, b_len;
a_len = mutt_strlen(a);
b_len = b ? strcspn(b, " \t\n\v\f\r") : 0;
return ascii_strncasecmp(a, b, MAX(a_len, b_len));
Either should be OK; I don't care much. Both improve on what's there now.
