[Groff] Problem with MM spacing with macro immediately after a heading (H)

[Damian McGuckin]

Around August 2014, there was a discussion started by Blake McBride

        Problem with MM spacing

I looks like Werner fixed something but I cannot exactly figure out what 
it was from that discussion.

The problem I have could be related but it is subtly different.

Let me know if I should really append to that thread.

I am using the latest 1.22.3. I did not have this problem previously when 
I was using a much older version of groff, the one which comes with RedHat 
6, or CentOS 6. But it is the first time I am using this new version with
some old files.

If I have something like

        .H 2 "A Heading"
        Some words of wisdom and ramblings ...

everything just rocks.

However, if I have

        .H 2 "A Heading"
        .TS
        .\" some table of something
        .....
        .TE
or
        .H 2 "Another Heading"
        .DS 0
        .\" some display which needs to be done literally
        .....
        .DE

then the spacing gets messed up.  Mind you, typing

        .rm address@hidden

at the start of the document fixes it quick smart, but that is not a real
fix. And heaven only knows what that really does to other things.

While I think a table or a display without some leading explanatory text 
is pretty poor style, and something I normally avoid, I use this document
structure for staff CVs.

This simple example highlights the problem. Any hints as to a fix is 
welcome.

.\" Start of Example
.S 12 14
.\" .rm address@hidden
.ds HF 3 3 3 2 2 2 2
.ds HP 12 12 12 12 12 12 12
.H 1 "Here Is An Example"
.\" Adding text here avoids the problem, but this is not always feasible.
.DS 0
This should be only one line under the heading.
This is not so unless you uncomment the '.rm' above.
.DE
What is the real fix please?
.\" Finish of example
