[PATCH 0/9] cex: shift derivation vs reduce derivation

The main goal of this series of commits is to go from

    Example              exp '+' exp • '/' exp
    First derivation     exp → [ exp → [ exp '+' exp • ] '/' exp ]
    Second derivation    exp → [ exp '+' exp → [ exp • '/' exp ] ]

to

    Example              exp '+' exp • '/' exp
    Shift derivation     exp → [ exp '+' exp → [ exp • '/' exp ] ]
    Reduce derivation    exp → [ exp → [ exp '+' exp • ] '/' exp ]

i.e., to show the shift case first, and labelled as such.  We should
probably also display the number of the rule being reduced, included
in r/r conflicts.  Future work.

Akim Demaille (9):
  tests: beware of version numbers from git describe
  cex: minor style changes
  cex: use better type names
  cex: minor renaming
  cex: more consistent memory allocation/copy
  cex: use state_item_number consistently
  cex: factor memory allocation
  style: s/lookahead_tokens/lookaheads/g
  cex: display shifts before reductions
