Done this now, see attached patch
(also contains my older patch for regexp and a few minor tweaks to other
files (e.g. -include to -include_lib so I could recompile it easily)

math:base/2 returns the same (goofy) error codes as
httpd_util:hexlist_to_integer/1 and httpd_util:integer_to_hexlist/1

It does NOT, however, simulate the what-I'd-consider-broken behaviour of
httpd_util:hexlist_to_integer/1:

Eshell V5.2.3.3  (abort with ^G)
1> httpd_util:hexlist_to_integer("3G5").
3
2> httpd_util:hexlist_to_integer("-3F5").
0

Instead it returns 'error' or 'not_a_num' for negative values, as the
httpd_util functions do, on the errors that they do detect.
