[NTG-pdftex] do we need pdfTeXk?

TeXk is there since it is a modified TeX and therefore (i guess) it had to be given a different name. Does a similar formal or other reason exist for pdfTeXk vs. pdfTeX? If not, we could change all "pdfTeXk" containing messages to "pdfTeX", as done already with the "e". The various "k" features, like "%&-line parsing enabled." are anyway individually flagged at program start. Regards, Hartmut
