[PATCH 4/4] line-log: simplify condition checking for merge commits

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

In process_ranges_arbitrary_commit() the condition deciding whether
the given commit is not a merge, i.e. that it doesn't have more than
one parent, is head-scratchingly backwards, flip it.
