-/* Compare strings A and B as file names containing version numbers,
-   and return an integer that is negative, zero, or positive depending
-   on whether A compares less than, equal to, or greater than B.
-
-   Use the following version sort algorithm:
-
-     1. Compare the strings' maximal-length non-digit prefixes lexically.
-        If there is a difference return that difference.
-        Otherwise discard the prefixes and continue with the next step.
-
-     2. Compare the strings' maximal-length digit prefixes, using
-        numeric comparison of the numbers represented by each prefix.
-        (Treat an empty prefix as zero; this can happen only at string end.)
-        If there is a difference, return that difference.
-        Otherwise discard the prefixes and continue with the next step.
-
-     3. If both strings are empty, return 0.  Otherwise continue with step 1.
-
-   In version sort, lexical comparison is left to right, byte by byte,
-   using the byte's numeric value (0-255), except that:
-
-     1. ASCII letters sort before other bytes.
-     2. A tilde sorts before anything, even an empty string.
-
-   In addition to the version sort rules, the following strings have
-   special priority and sort before all other strings (listed in order):
-
-     1. The empty string.
-     2. ".".
-     3. "..".
-     4. Strings starting with "." sort before other strings.
-
-   Before comparing two strings where both begin with non-".",
-   or where both begin with "." but neither is "." or "..",
-   suffixes matching the C-locale extended regular expression
-   (\.[A-Za-z~][A-Za-z0-9~]*)*$ are removed and the strings compared
-   without them, using version sort without special priority;
-   if they do not compare equal, this comparison result is used and
-   the suffixes are effectively ignored.  Otherwise, the entire
-   strings are compared using version sort.  When removing a suffix
-   from a nonempty string, remove the maximal-length suffix such that
-   the remaining string is nonempty.
-
-   This function is intended to be a replacement for strverscmp.  */

-   terminated by '\0', and similarly for BLEN.  */
