[PATCH 04/22] mailmap doc: start by mentioning the comment syntax

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Mentioning the comment syntax and blank line support first is in line
with how "git help config" describes its format. See
b8936cf060 (config.txt grammar, typo, and asciidoc fixes, 2006-06-08)
for the paragraph I'm copying & amending from its documentation.
