[NTG-context] messages on undefined control sequences

[Pablo Rodriguez]

Hans,

this is a standard eror message now:

 tex error       > tex error on line 9 in file cont-yes.mkiv: Undefined
 control sequence

Would it be possible that LMTX adds the undefined command at the end of
the tex error line? I mean something similar to:

 tex error       > tex error on line 9 in file cont-yes.mkiv: Undefined
 control sequence (vskivskip)

It would help a lot to detect wrong commands.

Many thanks for your help,

Pablo
