Math fonts needs surrounding {-}

[AndreG-P]

I'm still working with latexmlc and it works fine. Here is my input:

latexmlc \
  --includestyles\
  --format=xhtml\
  --whatsin=math\
  --whatsout=math\
  --pmml\
  --cmml\
  --nodefaultresources\
  --linelength=90\
  --preload=LaTeX.pool\
  --preload=article.cls\
  --preload=amsmath.sty\
  --preload=amsthm.sty\
  --preload=amstext.sty\
  --preload=amssymb.sty\
  --preload=eucal.sty\
  --preload=[dvipsnames]xcolor.sty\
  --preload=url.sty\
  --preload=hyperref.sty\
  --preload=[ids]latexml.sty\
  --preload=texvc\
  literal:"\frac{a}{b}"

However, when I enter \mathbf{x} there is a warning about "mathbf" should only appear in math mode and the output is a html fragment. Same for \mathcal{x}. When I enter {\mathbf{x}} everything works again...

Thanks for the report. Looks like the math guards of --whatsin=math may need a fresh look
