macro2m4.py: normalize indention of quoted sections

Macro documentation may contain "quoted" paragraphs that will be typeset in
verbatim. Such quoted paragraphs ought to be indented by (at least) one blank.
The number of blanks that macro authors used in their submissions varies,
though. This patch normalizes all indented sections to 2 blanks.
