git hash-object used to process the --stdin command line argument
before reading subsequent arguments. This caused 'git hash-object
--stdin -w' to fail to actually write the object into the
database, while '-w --stdin' properly did. Now git hash-object
first reads all arguments, and then processes them.
This regresses one insane use case. git hash-object used to allow
multiple --stdin arguments on the command line:
$ git hash-object --stdin --stdin
foo
^D
bar
^D
Now git hash-object errors out if --stdin is given more than once.
