I am terribly sorry to bother you about formatting issues (in my mind, it
is quite an annoying thing that we still have no fully automatic way to
format Git's source code according to Git's preferred coding style, but
there you go...): this `DEFAULT_GIT_DIR_ENVIRONMENT` should be aligned
with the first parameter of `die()`, i.e.

+		if (!nongit_ok)
+			die(_("not a git repository (or any of the parent directories): %s"),
+			    DEFAULT_GIT_DIR_ENVIRONMENT);

Likewise, `dir.buf` should be aligned with the `_` two lines above.

Otherwise I think this patch is good to go!

Thank you,
Johannes
