Task for this weekend:

https://movq.de/v/b05a7ce782/vid-1758959332.mp4

When you call man ascii, you get this nice table, but there’s a weird vertical line at the bottom. That line is supposed to be a vertical rule and is supposed to go from the bottom of the table all the way to the top.

Let’s see if I can debug this. (Not getting my hopes up at this point, but I’ll try.)

(#qchnx6q) @movq@www.uninformativ.de Is this for your own OS? 🤔

(#qchnx6q) @prologic@twtxt.net No, this is a Linux manpage from the man-pages project: https://git.kernel.org/pub/scm/docs/man-pages/man-pages.git/tree/man/man7/ascii.7

I do have an idea what’s going on. Could be an unfortunate interaction between the table preprocessor tbl and the man macro package. 🤔

(#qchnx6q) Okay, now that I knew what to look for, I found existing bug reports:

• https://lists.gnu.org/archive/html/groff/2023-04/msg00400.html
  
• https://savannah.gnu.org/bugs/?63960
  

Most importantly:

This is resolved in the groff trunk.

🥳

(#qchnx6q) @movq@www.uninformativ.de I got an empty line through the table, similarly to one of the linked bug reports, just at a different location:

(#qchnx6q) @lyse@lyse.isobeef.org That looks like an older bug report. Which groff version is that (groff --version)?
