    Make Lexer.x more like the 2010 report · 64c9898f
    thomie authored
    Summary:
    I tried reading the lexer and the 2010 report side-by-side. Althought I didn't
    quite finish, here are some small discrepancies that I found.
    
    This revision may be low priority for reviewers, but having these commits just
    in my local repository does no good either.
    
    Changes:
    * $nl was defined, but not used anywhere
    * formfeed is a newline character
    * add \: to $ascsymbol
      For simplification reason, the colon (':') was added to the character
      set $ascsymbol in the 2010 report. Here we make the same change.
    * introduce the macros `qvarid`, `qconid`, `qvarsym` and `qconsym`
    * foreign is a Haskell keyword
    * add/update comments
    
    Test Plan: Harbormaster (is awesome)
