The lexer mishandled cases like "#x1E+2", because "E" is
not an exponent marker for hexadecimal --- and it has been that
way forever, but the repair isn't all that difficult.
better wrt to its first result
That is, instead of just returning the string "#lang" it now
returns the actual text that was there (it was supposed to be
doing that all along and my recent commit fixed it, but I
missed the test cases)
and change the tests so they all run with port line
counting enabled (or else the unicode test fails)
adjust module-lexer.rkt tests so they can run in either
port-counting mode or not (but currently run them all in
port-counting mode because scheme-lexer doesn't work without it)
also make a first stab at what needs to change in the module
lexer to make it work in non port line-counting mode
'read-language' uses as a single token in the case that read-language
fails. This helps it to deal with things like s-exp and at-exp
properly
closes PR 12260
with drdr
also change two of the failing tests so they pass, but incorrectly and
add a note there to that effect so if someone does fix that eventually
they won't be confused (I hope)
* Another big chunk of v4-require-isms
* Allow `#lang framework/keybinding-lang' for keybinding files
* Move hierlist sources into "mrlib/hierlist", leave stub behind
