textual -- parser bits fixes

[Fred T. Hamster]

parser bits:

1. quotes_parsing_as_func
   1. what if the name in the command line has a space?
   2. we need a thing for parsing quotes that can consume an existing string. or skate along an existing string to point out where last quote is.
   3. just rip out the code in tokenizer and make it this. then use the new quoting code for tokenizer again.
   4. this is needed as separate support that can be relied on.
2. move the indentation bit into here.
   1. actually, move it from utility into the textual lib, but in some kind of formatting or outputting file.
   2. that's where a lot of some of this stuff should go.
3. test the new function, to make sure the translate cr for plat thing works.
