bug: "rev-parse --short" with "--not --remote"

Hello,

I noticed what appears to be a bug in rev-parse with an admittedly somewhat unusual combination of arguments.

Compare the output of the following:

% git rev-parse HEAD --not --remotes=origin 3de09080eb219149a8596dc21915d5a496cba171 ^4fb157bf360413fe3fad38d03b02ce7232d12961 ^757cfa6938c3d510d1597096d9f0b6878b884270

To this:

% git rev-parse --short HEAD --not --remotes=origin ^4fb157b ^757cfa6 ^3de0908

In the first case rev-parse emits the commit-id of HEAD, followed by negated commit-ids of all remote branches in origin.  I believe this is the correct and intended behavior.

In the second case rev-parse emits the negated short commit-ids of all remote branches in origin, followed by the negated short commit-id of HEAD.  This is inconsistent with the results of the (presumably correct) prior example.

I would expect both commands to emit the same output, modulo the number of characters emitted for the commit-id.

Thank you, Brent Casavant
