Title:
  seq record doesn't process LNK0 in "Specified" mode

Status in EPICS Base:
  In Progress

Bug description:
  While updating the seq record reference documentation, we noticed that
  if one tries to use a seq record in "Specified" mode, the LNK0 will
  never be processed, regardless of the OFFS field.

  Possible cause in src/std/rec/seqRecord.c:

          if (prec->selm == seqSELM_Specified) {
              int grpn = prec->seln + prec->offs;
              if (grpn < 0 || grpn >= NUM_LINKS) {
                  recGblSetSevr(prec, SOFT_ALARM, INVALID_ALARM);
                  return asyncFinish(prec);
              }
              if (grpn == 0)
                  return asyncFinish(prec);

              lmask = 1 << grpn;
          }

  (code from branch 3.15)
