[NTG-context] # verbatim typesetting

[Marcus Vinicius Mesquita]

Dear List,

The MWE below gives a pdf with two #'s instead of only one. Why is that?

\starttext

\startluacode
    context.type("#")
\stopluacode

\stoptext

corpo nem seus membros, por ser descanso da alma, primavera do
coração, distração do aflito, entretenimento do solitário, e viático
do viajante.

because by default tex loves to duplicate hashes when it serializes 
token lists

as this seems to be "the month of the duplicate hashes" i looked it what 
we did so far can also work here and i sort of managed although there 
might be more cases (when im done with this we probably "have it the 
other way around" which could mean adapting some code in the tex-lua 
context system that actually depends on duplication or where we work 
around it and no longer need to)

the complication is mostly in moving token lists around, them beign 
serialized and deserialized etc but i guesa at some point we'll get 
there (original tex doesn't really have this problem because there 
serialization hashes will triggere errors in cases where they are not 
permitted anyway)

no upload as i need to test more

Hans
