That's not bad. A couple of notes from my "just now" testing:

1) Needs better error handling if the node doesn't exist. I tried
running it for "gawk" (on a system where GAWK was not installed at the
system level) and it generated a blank screen.

Note that "info gawk" (without the fancy options and piping as above)
gets to a screen telling you about the nodes that do exist. But
somehow, this screen gets lost in the shuffle when the above options and
piping are used.

2) You need "less -R", or else you get weird stuff displayed by less.

P.S. Hmmm. I just tried "info gawk" on a system where GAWK *is* installed
at the system level and it still bombed out. Weird.

HererCOs a handy example command for viewing a man page in a nicely typeset rendering:

gunzip -c $(man -w bash) | groff -ktman -Tpdf | okular -

What would be an equivalent for info?

I don't know, but here is a simpler version of the above pipeline:

man -Tpdf bash | xpdf /dev/stdin

I've meanwhile looked also into the size of the man pages...

Number of man pages with number of lines
512 with 1..40 lines
1641 with 41..200 lines
781 with 201..1000 lines
159 with 1001..5000 lines
28 with 5001..20000 lines

That doesn't appear to be just irrelevant information, at least.

Is that 20000 tight? That is, are there man pages that big, or did your histogramization (?) arbitrarily pick 20000?

$ man txr | wc
46266 382645 2775327

No, hold it, correction. I have a wide terminal. We have to measure
using the 80 column standard:

$ MANWIDTH=80 man txr | wc
67616 386241 3110809

That's more like it!

I don't have txr on my system, but :

$ MANWIDTH=80 man ffmpeg-all 2>/dev/null | wc
49196 210446 1764012

That omits the troff "cannot break line" and "cannot adjust line"
warnings.
