1.23.0.rc1.2875-9c30-dirty: does not prefer its own same-version subprograms?

[Steffen Nurpmeso]

Hello.

Gratulations for maintainership, Branden Robinson!

I am in the process of porting mdocmx to groff 1.23.

(That is to say: automake issues, after gnulib issues, git gc
--aggressive is killed by that ChangeLog which is nothing but
a duplicate of git log but prepends at the top instead of
appending to the file, 13.7 GB RAM and > 30 minutes for GCing that
file alone, i think describes my problem.)

Letting aside that --with[out]-doc was blindly removed even though
i do not really think that so much changes to the involved
documents happened, which is a pity, since i have to fiddle around
until autoreconf / make succeed, sigh, ...  But i do not think
that is the cause for the problem below.

I see this:

  #?0|kent:src$ ll -l `command -v groff`
  -rwxr-xr-x 1 root root 108288 Mar 24  2019 /usr/bin/groff*

Groff of my Linux distro.

  #?0|kent:src$ ll -l `command -v s-roff.old`
  lrwxrwxrwx 1 steffen steffen 23 May 16  2019 
/home/steffen/usr-kent-crux-linux-x86_64/bin/s-roff.old -> 
../opt/.groff/bin/groff*

A version of 1.22.3 with my 2015 mdocmx patch.

  #?0|kent:src$ ll -l `command -v s-roff`
  lrwxrwxrwx 1 steffen steffen 27 Sep  3 23:20 
/home/steffen/usr-kent-crux-linux-x86_64/bin/s-roff -> 
../opt/groff-1.23/bin/groff*

1.23 RC1 with mdocmx "regulary" implemented (under contrib/ etc;
of course tmac/ mdoc(7) had to be patched in-line, but that
surprisingly took not even an hour and is "3 files changed, 153
insertions(+), 51 deletions(-)"), no more.

So this:

Ditto for tmac, somehow.  I just discovered it freshly.

Other than that i like your OSC 8 implementation, Branden!

With one problem, i wonder what could be done to give an empty
URL, ie only an id=ID.  for now i use the char #.  Somehow i have
not working it like so yet, but in the works!

Thanks for implementing OSC 8 in grotty!
