Follow the Oxford style, which says to use "up-to-date" before the noun,
but "up to date" after it. Don't change plumbing (specifically
send-pack.c, but transport.c (git push) also has the same string).

This was produced by grepping for "up-to-date" and "up to date". It
turned out we only had to edit in one direction, removing the hyphens.

Fix a typo in Documentation/git-diff-index.txt while we're there.

Defining USE_ASCIIDOCTOR=1 when building Git uses asciidoctor over
asciidoc when generating DocBook and man page documentation.  However,
the contrib/subtree module does not presently honour that flag.

This causes a build failure when asciidoc is not present on the build
system.  Instead, adapt the main Documentation/Makefile logic to use
asciidoctor when requested.

We prefer a space between the function name and the parentheses, and no
space inside the parentheses.

The opening "{" should also be on the same line.

Prefer "test" over "[ ... ]", use double-quotes around variables, break
long lines, and properly indent "case" statements.

"git merge" in v2.9 prevents merging unrelated histories.

"git subtree split --rejoin" creates unrelated histories when
creating a split repo from a raw sub-directory that did not
originate from an invocation of "git subtree add".

Restore the original behavior by passing --allow-unrelated-histories
when merging subtrees.  This ensures that the synthetic history
created by "git subtree split" can be merged.

Add a test to ensure that this feature works as advertised.

The "split" subcommand of "git subtree" (in contrib/) incorrectly
skipped merges when it shouldn't, which was corrected.

"git subtree" (in contrib/) records the tag object name in the
commit log message when a subtree is added using a tag, without
peeling it down to the underlying commit.  The tag needs to be
peeled when "git subtree split" wants to work on the commit, but
the command forgot to do so.
