Add support for white spaces in tex commands

[koppor]

I have

\tcbinputlisting{%
  listing only,
  listing file=\currfilepath,
  colback=green!5!white,
  colframe=green!25,
  coltitle=black!90,
  coltext=black!90,
  left=8mm,
  title=Corresponding \LaTeX{} code of \texttt{\currfilepath},
  minted language=TeX,
  minted style=vs,
  minted options={
    fontsize=\footnotesize,
    firstline=\the\LTGbeginlineexample,
    lastline=\the\LTGendlineexample,
    firstnumber=\the\LTGbeginlineexample,
    breaklines,
    linenos,
    numbersep=8pt
  }
}

I configured

add-tex-command tcbinputlisting ppppppppppppppppppppppp
add-tex-command "minted options" ppppppppppppppppppppppp

aspell still goes into tcbinputand minted options - and complains that fontsize is an unknown term.
