[texhax] Detection of start of source line

This may help -- at least it generates no run-time errors :

\def \treatasteriskspecially

{ % space needed here

\ifx *\nexttoken

\let \nexttoken = \item

\else

\def \nexttoken {\char `\*}

\fi

\nexttoken

}

\catcode `\^^M = \active \def ^^M{\futurelet \nexttoken \treatasteriskspecially}

abcd * efgh

* ihjk * lmno

\end
