Comment 1 for bug 1794196

Ralph's commit 45415512 seems to be the culprit; the modifications to special() to add the SIMM field look to have been written without realizing that the *VL fields are also marked SPC_MOD in the mbbi and mbbo records. Previously special() returned 0 for these fields, but now it is returning an error.

Patch attached to return the special() routines to doing the right thing. I will apply after Mark Rivers confirms it fixes the problem for him. I haven't checked any other record types.
