This is the default if MathJax is not turned on or tex4ht or latex2html
are not used.  The <em> tag marks the text as separate.  There is not
much more that could be done - texi2any does not itself interpret
TeX math notation at all and is not going to format e.g. digits
differently.

My advice is to use MathJax when generating the manual as described in
the same part of the manual.
