[bug #40793] "groff -mandoc -Thtml ..." produces huge fonts

[Bjarni Ingi Gislason]

Follow-up Comment #2, bug #40793 (project groff):

  1) There is a bug in the man page "gcc(1)".  The definition of the
string "C*" uses "\s0" instead of an absolute change (here "\s+2").

  2) The bug in "grohtml" (post-grohtml) is seen in this simple example
(in gcc(1) it is "\*(C+ \s-1ABI\s+1")

.pl 10v
Begin \s-2UPPER\s+2 \s-1lower\s+1 normal

  Output from "test-groff -Thtml <file>" :

...
<hr>


<p>Begin <small>UPPER</small> lower <big>normal</big></p>
<hr>


  Output from "test-nroff -Thtml -Z <file>":

...
f1
s10
V80
H0
md
tBegin
ws8
h24
tUPPER
ws9
h24
tlower
ws10
h24
tnormal
n40 0
x trailer
V400
x stop

  1) Font size changes around a space (' ', '\ ', '\0', and "\h'2n'")
are summed to one size change.

  2) The postprocessor must know (check) the normal (default) font size
to avoid adding "<big>" or "<small>"
