Jeff King 9ab89a2439 log: enable "-m" automatically with "--first-parent"
When using "--first-parent" to consider history as a single line of
commits, git-log still defaults to treating merges specially, even
though they could be considered as single commits in the linearized
history (that just introduce all of the changes from the second and
higher parents).

Let's instead have "--first-parent" imply "-m", which makes something
like:

  git log --first-parent -p

do what you'd expect. Likewise:

  git log --first-parent -Sfoo

will find "foo" in merge commits.

No new test is needed; we'll tweak the output of the existing
"--first-parent -p" test, which now matches the "-m --first-parent -p"
test. The unchanged existing test for "--no-diff-merges" confirms that
the user can get the old behavior if they want.
