update-ref: allow --no-deref with --stdin
If passed both --no-deref and --stdin, update-ref would error out with a general usage message that did not at all suggest these options were incompatible. The manpage for update-ref did suggest through its synopsis line that --no-deref and --stdin were incompatible, but it sadly also incorrectly suggested that -d and --no-deref were incompatible. So the help around the --no-deref option is buggy in a few ways. The --stdin option did provide a different mechanism for avoiding dereferencing symbolic-refs: adding a line reading option no-deref before every other directive in the input. (Technically, if the user wants to do the extra work of first determining which refs they want to update or delete are symbolic, then they only need to put the extra "option no-deref" lines before the updates of those refs. But in some cases, that's more work than just adding the "option no-deref" before every other directive.) It's easier to allow the user to just pass --no-deref along with --stdin in order to tell update-ref that the user doesn't want any symbolic ref to be dereferenced. It also makes the update-ref documentation simpler. Implement that, and update the documentation to match.
