Mark Whitley 97562bd9d7 - Added support for backreferences in substitution expressions up to nine ... (\1, \2...\9). This touched a lot of places in this file and I added a new function 'print_subst_w_backrefs' in order to keep 'do_subst_command' a little more tidy. * I tested this good 'n hard, but will always appreciate more testing from other, willing folks. - Noticed that the index_of_next_unescaped_slash was subtly wrong so I changed both the functionality and behavior (it used to skip over the first char in the string you passed it, assuming it was a leading '/'--this assumption is no longer made) this necessitated changing the lines that call this function just slightly.		2000-07-17 20:06:42 +00:00
