docs(gen_help_html.lua): h4 pseudo-heading layout

Problem:
The <br> hack in a0c64fe816f8 causes weird layout if a "h4 pseudo-heading"
is not the only tag on the line. For example in the help text below, the
"*'buflisted'*" tag was treated as h4 and followed by <br>, which is
obviously wrong:

                            *'buflisted'* *'bl'* *'nobuflisted'* *'nobl'* *E85*
    'buflisted' 'bl'    boolean (default on)

Solution:
Only treat a tag as "h4 pseudo-heading" if it is the only tag in the
line. This is fragile, but in practice seems to get the right balance.
