Indeed. /etc/groff/man.local contains: . if '\V[GROFF_SGR]'' \ .output x X tty: sgr 0 so the solution is to define a GROFF_SGR evironment variable.

Well, here's one of them. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=312935 ...with my lengthy rebuttal and defense of groff's behavior.

Multi-columns in ms, again
Dear All,
in April 29, I asked whether there is a possibility to resume one-column
text after a two-column text on the same page. Your answers, uni sono,
said what the the manual says: returning to one-column mode will always
finish the page and begin a new one.
The reason for this behaviour is to "[m]ake sure we don't exit if there
are still floats or footnotes left-over." (line 578 of s.tmac, groff
1.22.4)*
I am by far not familiar enough to modify the macros in s.tmac, so may I
kindly ask for some guidance?
Task: create a private 1C-style command which
- perhaps named .1Cs ("s" as in simplified or stripped down)
- flushes the material not yet typeset, happily ignoring any floats
of footnotes, in two balanced columns; certainly using .pg*end-col, I
assume?
- returns to one-column mode, trusting that
- my file is a clean text file without surprises, so need to take
care of footnotes etc.
I could start with line 527 of s.tmac, that's where the definition of
.1C starts.
But how many lines between 527 and 601 do I really have to copy into a
private macro definition file? While I understand individual definitions
(the macro names are quite transparent) I fail to make sense of how
everything works together.
Thank you very much for your occasional enlightenment,
Best regards,
Oliver.

upgraded to groff 1.23. It will happen.

Re: Multi-columns in ms, again
Dear All,
in a follow-up to myself:
If I understood where the whole .1C definition ends, I could copy that
block into an own macro definition and from there eliminate just those
commands which flush the old page and begin a new page. I could even
ignore the tests for floats and footnotes because no such thing will
appear in my text.
Or I am completely, utterly and totally mistaken?
Best regards,
Oliver.
PS: Why do I want to do that? I am translating a scientific paper which
by all appearance seems to be typeset with a troff-like system. It is
typeset in two columns (except for title and abstract), and in the
center of one of the pages there is a table which, while not being very
high, spans across the whole page. The order of text blocks respects the
table and shows the following pattern:
TEXT 1 TEXT 2
VERY WIDE TABLE
TEXT 3 TEXT 4
For the convenience of the reader of the translation (who has access to
the original and might want to check a few numbers) I'd like to
reproduce the layout.
If that is really not possible, I still can shift the very wide, but not
very high table to the end.

Re: Multi-columns in ms, again
Another follow-up:
I just checked the one-column mode across the macro packages ms, me and
mm, and lo and behold, the mm man page tells me:
1C [1] Begin one-column processing. A 1 as an argument disables
the page break. Use wide footnotes, small foot‐
notes may be overprinted.
I never worked with the mm package. I'll give it a try.
Best regards,
Oliver.

Re: Multi-columns in ms, again
Dear All,
I tried the mm macros.
In general, the idea to have a horizontal object spanning the full page
width between two portions of text in two columns can be realized with mm.
The .1C 1 macro with the argument "1" does the trick. There is one
caveat, though. mm does not balance columns, so I have to insert a break
manually.
This should now be an obstacle of minor concern.
Best regards,
Oliver.

Re: Multi-columns in ms, again
Dear All,
I am not going to bother you anymore with my column journey.
.NCOL
in the mm package does the trick. It allows breaking a column, and since
this is a one-time task, I do not mind searching for the optimal
breakpoint by hand.
All my questions of April 29 answered! Thank you all for your patience!
Best regards,
Oliver.
PS:
So, in mm, a document would contain the following commands:
Text text text text
.\" and now switch to two columns
.2C
Text text text text
and so on
.\" search for best balance of columns manually
.NCOL
Some more text
.\" Switch to one-column mode
.1C 1
.TS
.\" Your wide table here
.TE
.\" And back to two-column mode.
.2C
Rest of the text
