[NTG-context] Parsing \...luacode within a \def

Hi Lukáš,

I am not sure but I guess that the problem is related with the behaviour of
the input processor which erases characters at the end of line (CR, LF) and
replace them by a space. Then, the whole content between \start/stopluacode
is at only one line. If you the second way of comment marks, the letter "u" 
will be shown at the output.

Tomáš 

\def\U{%
  \startluacode
--[[ blahblah
]]--

    context("u")
  \stopluacode
}

# Hello,
# 
# I encountered a phenomena that I cannot understand. Let's have the following code:
# 
# ----
# \def\T{%
#   \startluacode
#     context("t")
#   \stopluacode
# }
# 
# \def\U{%
#   \startluacode
#     --
# 
#     context("u")
#   \stopluacode
# }
# 
# \starttext
#   A
#   \startluacode
#     --
# 
#     context("b")
#   \stopluacode
#   \T
#   \U
# \stoptext
# ----
# 
# This gives "Abt" - but there is no "u".
# 
# It seems that the (first) comment mark "--" within a \startluacode within \def (here: \def\U) causes all code till \stopluacode is being ignored.
# 
# But why?
# 
# Maybe I'm missing something very basic...
# 
# Best regards,
# 
# Lukas
