parser: factor out function that parses right-hand side of prefix/infix ops

These two had common pattern. The significant difference was just a result
expression:

  prefix: (op-name, rhs)
  infix:  (op-name, lhs, rhs)

Test argument handling and various data parsing

Mercurial earlier than 2.7 by renaming ".hg/histedit-state"
