Documentation/git-pull: clarify configuration

The sentence about 'branch.<name>.rebase' refers to the first sentence
in the paragraph and not to the sentence about avoiding rebasing
non-local changes. Clarify this.

 --rebase::
-	Instead of a merge, perform a rebase after fetching.  If
-	there is a remote ref for the upstream branch, and this branch
-	was rebased since last fetched, the rebase uses that information
-	to avoid rebasing non-local changes. To make this the default
-	for branch `<name>`, set configuration `branch.<name>.rebase`
-	to `true`.
+	Rebase the current branch on top of the upstream branch after
+	fetching.  If there is a remote-tracking branch corresponding to
+	the upstream branch and the upstream branch was rebased since last
+	fetched, the rebase uses that information to avoid rebasing
+	non-local changes.

+See `branch.<name>.rebase` in linkgit:git-config[1] if you want to make
+`git pull` always use `{litdd}rebase` instead of merging.

 [NOTE]
 This is a potentially _dangerous_ mode of operation.
