[PATCH] rev-list-options.txt: use correct directional reference

["SZEDER Gábor" <szeder.dev@gmail.com>]

The descriptions of the options '--parents', '--children' and
'--graph' say "see 'History Simplification' below", although the
referred section is in fact above the description of these options.

Send readers in the right direction by saying "above" instead of
"below".
