.git/shallow. This option updates .git/shallow and accept such
refs.
+--negotiation-tip=<commit|glob>::
+ By default, Git will report, to the server, commits reachable
+ from all local refs to find common commits in an attempt to
+ reduce the size of the to-be-received packfile. If specified,
+ Git will only report commits reachable from the given tips.
+ This is useful to speed up fetches when the user knows which
+ local ref is likely to have commits in common with the
+ upstream ref being fetched.
++
+This option may be specified more than once; if so, Git will report
+commits reachable from any of the given commits.
++
+The argument to this option may be a glob on ref names, a ref, or the (possibly
+abbreviated) SHA-1 of a commit. Specifying a glob is equivalent to specifying
+this option multiple times, one for each matching ref name.
++
+See also the `fetch.negotiationAlgorithm` configuration variable
+documented in linkgit:git-config[1].
