I  am  terribly  sorry,  but again this patch is not
perfect. The addition of a .ti request has caused  a
redundant  vertical  space, 1v in nroff mode. I have
made a work-around for it:

    .de address@hidden
    .\" retain temporary indentation
    .if !(\\n[.in]-\\n[.i]=0) .nr misc*ti \\n[.in]
    .vpt 0
    .DEVTAG-\\$1 \\$2
    .if r misc*ti \{
    .  ti \\n[misc*ti]u
    .  rr misc*ti
    .  sp -1
    .  \}
    .sp -1
    .vpt 1

Maybe it would be better  to  have  another  'local'
numeric  register  to accumulate vertical indent and
then call .sp only once at the end... I'll do it  if
groff will 'like' such an optimization.

I have tested it in nroff mode and made sure that it
generates exactly the same output as  the  unpatched
m.tmac with all DEVTAG calls removed, i.e eliminates
all visible effect of tags.

I have attached an archive  (  containing
the test file I was using ( and the result
I am getting with it (hdtest.txt). Also attached  is
the corresponsing diff file for m.tmac.
