[NTG-context] Minor bug in Lua or ConTeXt

[Bruce Horrocks]

Thanks Hans.

Before Pablo spends too much effort on the wiki it's worth pointing out that this only happened because I was in-line documenting the Lua function that I had written and wanted to name the ConTeXT macro that would invoke it - so it's trivial for me to avoid this error.

Perhaps the Wiki only needs to point out that if you get a Lua related error and the error log lists the entire contents of \startluacode ... \stopluacode then a possible source of the error is a \command somewhere in there?

Regards,
