Hi Eric,

Thanks for the longer explanations. It really makes clear that a "rescanning"
process occurs - something which helps understanding m4.

Here are two minor tweaks of the text, to make it clear that
  - the intent of the second snippet is the same as of the first one,
  - the capitalization occurred in both cases, only at different moments.
