[PATCH 0/4] Improve documentation

[Akim Demaille]

Some of the examples are showing their age, let's modernize them.
Also, let's provide an intermediate level example in C.  While at it,
improve the management of the examples.

  examples: fix annoying off-by-one errors
  examples: add a simple infix calculator in C
  doc: modernize the examples
  doc: a single space before closing comments
