[NTG-context] another error message in LMTX

[Pablo Rodriguez]

Hans,

using latest from yesterday, I get the following error:

 tex error       > tex error on line 22 in file cont-yes.mkiv: Valid
 keyword expected, likely 'minus'

 <lua output> mt
     xrunjit
 <to be read again>
     \relax
 <macro> \buff_verbatim_type_buffer_indeed ...rrentregime
 }tab{\typingparameter \c!tab }method{\p_buff_option
 }escape{\typingparameter \c!escape }nature{display}\relax
     \dostoptagged \endofverbatimlines \dostoptagged \stoppacked
     \typingparameter \c!after

 [...]

 You started a keyword but it seems to be an invalid one. The first
 character(s) might give you a clue. You might want to quit unwanted
 lookahead with \relax.

This comes from a book with > 300pp. It compiles perfectly fine with
MkIV, so the typo might be in LMTX itself.

I wonder whether it would be possible to add the invalid keyword (and
related command) to the error message. This would mean something like:

 tex error       > tex error on line 22 in file cont-yes.mkiv: Valid
 keyword expected, got "invalid one" (related to "command").

This would help a lot to figure out where to start searching for clues
for a MWE.

Many thanks for your help,

Pablo
