The refname value is relative to $GIT_DIR; e.g. for the master
head this is "refs/heads/master". The two sha1 values before
each refname are the object names for the refname before and after
-the update. Refs to be created will have sha1-old equal to 0{40},
-while refs to be deleted will have sha1-new equal to 0{40}, otherwise
+the update. Refs to be created will have sha1-old equal to 0\{40},
+while refs to be deleted will have sha1-new equal to 0\{40}, otherwise
sha1-old and sha1-new should be valid objects in the repository.
This hook is called before any refname is updated and before any
head this is "refs/heads/master". The two sha1 arguments are
the object names for the refname before and after the update.
Note that the hook is called before the refname is updated,
-so either sha1-old is 0{40} (meaning there is no such ref yet),
+so either sha1-old is 0\{40} (meaning there is no such ref yet),
or it should match what is recorded in refname.
The hook should exit with non-zero status if it wants to disallow
head this is "refs/heads/master". The two sha1 values before
each refname are the object names for the refname before and after
the update. Refs that were created will have sha1-old equal to
-0{40}, while refs that were deleted will have sha1-new equal to
-0{40}, otherwise sha1-old and sha1-new should be valid objects in
+0\{40}, while refs that were deleted will have sha1-new equal to
+0\{40}, otherwise sha1-old and sha1-new should be valid objects in
the repository.
Using this hook, it is easy to generate mails describing the updates
