Which font are you using?
With all mono-spaced (fixed-width) fonts everything works fine. The problem
occurs just with  variable spaced fonts.

Btw I noted that the fix is not perfect: the table at the end of man(1) is
misaligned, with or without the fix. Even without calling col at all.

This could be due to troff assuming fixed with font and inserting spaces
instead of tabs. And its a pity, because  probably libframe would align
tabs properly.

But this is just a guess, I had no time to check the troff code for this
second issue.
