Hi Tassilo,

as I said to Mosè: perhaps in the future, some modifications could
be considered. In the specific case of my test file the Knuth TeX
error message

TeX capacity exceeded, sorry [grouping levels=255]

will remain always quite to the point. This is already nowadays not
quite the case of the LaTeX error message about memory matters.

I will ponder the addition of the line above to my .emacs, but
perhaps I will first make a reading of the database of error
messages in tex-dbg.el as mentioned in the link from Mosè's message.

Bye,

Jean-François
