Hm, isn't that this lucida rip off again? Maybe bad metricks then but I'm
not going to look into that as the official TUG lucida opentype fonts

The first sentence is irrelevant. And a guess. Bad metrics is not the
culprit
if it were true, the same problem would be under lualatex, correct?
well, who knows what (me)tricks those fonts have embedded .. are these the
official TUG lucida open type fonts? if so,
\setupbodyfont[lucida]
should just work (btw, you also don't set up math)
...
But it's not there.
I can't (and won't) check that as I don't have (lua)latex installed nor have
those fonts. I also don't see where this \qquad is in your example.
Using the same fonts under lualatex yields \TeX\ without an issue. 

\documentclass{article}

\usepackage{unicode-math}

\defaultfontfeatures{Ligatures=TeX}

\setmainfont[
      ItalicFont=LucidaBrightItalic,
        BoldFont=LucidaBrightDemiBold,
  BoldItalicFont=LucidaBrightDemiItalic,
  ]{LucidaBrightRegular}
%
\setsansfont[
      ItalicFont=LucidaSansOblique,
        BoldFont=LucidaSansDemiBold,
  BoldItalicFont=LucidaSansDemiOblique,
  ]{LucidaSansRegular}
%
\setmonofont[
%      ItalicFont=LucidaTypewriterOblique,
        BoldFont=LucidaTypewriterBold,
%  BoldItalicFont=LucidaTypewriterBoldOblique,
  ]{LucidaTypewriterRegular}

\begin{document}

{\rm    \input{knuth}}

\textsf{\input{knuth}}

\end{document}
...
As for the \showmakup ... it is used extensively and afaiks there are no
issues with it.
After running lualatex the problem dissappears. Or it seems like it.
