[NTG-context] small bugfix: module t-rsteps, more than 9 slides not possible

\FromStep[10] doesn't work in the following program: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \usemodule[rsteps] \setupcolor[state=start] \definehead[Subject][subject] \setuphead[Subject][page=yes,style=\bfb] \starttext \StartSteps[Title] a \FromStep[9]{b} \FromStep[10]{c} \StopSteps \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% The problem lies in: \def\FromStep[#1]{% \steps@updatenumber#1% ... The second line should be \steps@updatenumber(#1)% otherwise \steps@Updatenumber becomes only 1 as input and typesets the zero on the document. In the same art some more lines are to be fixed. Mojca
