hi Hadrien,

there's some generic(?) syntactic font lock getting triggered once the
doublequote character is found, that expects a closing doublequote - until then
everything is locked as a string. Is this what this bug is about (it was not
100% clear to me from your initial report) ? i'm attaching a patch that works
around this behavior but i don't know if it is the proper way to deal with the
problem (it certainly doesn't look pretty). The idea is to insert an additional
rule in tcl-syntax-propertize-function that will match the tcl-builtin-list
keywords ('puts' is in there among others) plus the brackets that follow, so
that if a doublequote is found in-between the brackets then there won't be any
automatic string locking that would mess up the closing brackets and everything
else (until another doublequote was found). Then in tcl-set-font-keywords a new
rule will match the brackets and any characters inside will be locked as a
string (including the single quote).
