flexfax: a possible bug with sendpage

[Chas Williams <chas@cmf.nrl.navy.mil>]

i am using hylafax-v4.0pl2 on a sparc solaris 2.6 system (gcc 2.7.2) and am
seeing a problem with sendpage and pagermap.  i wrote the following in
etc/pagermap:

(.*)@(.*)       \2/\1

however, this didnt work as expect, pagesend/hfaxd attempted to dial
\2 instead of the second regexp match.  see below:

Apr 17 09:43:59.01: [  903]: SESSION BEGIN 00000017 12022
Apr 17 09:43:59.02: [  903]: SEND PAGE: JOB 26 DEST \2 COMMID 00000017
Apr 17 09:45:01.88: [  903]: PAGE FAILED: No carrier detected
Apr 17 09:45:02.14: [  903]: SESSION END

apparently hfaxd only applies the regexp to the PIN and not the dial string.
the patch below fixes this (actually you might just apply subRHS() before
finding the / and splitting into a dialstring and pin, but this works and the
code was difficult to read)

                            if (re)                     // do substitutions

                                subRHS(pin, *re, pagerID);
-                               subRHS(number, *re, pagerID);
-                           }
                        } else {                        // <dialstring>
                            number = np;
                            pin = pagerID;

why do i need this?  not everyone has the same pager service and maintaining
the pagermap file for everyone would be very painful.
