OPTIONS

Operation Modes
~~~~~~~~~~~~~~~
Each of these options must appear first on the command line.
--parseopt::
Use 'git rev-parse' in option parsing mode (see PARSEOPT section below).
--sq-quote::
Use 'git rev-parse' in shell quoting mode (see SQ-QUOTE
section below). In contrast to the `--sq` option below, this
mode does only quoting. Nothing else is done to command input.
Options for --parseopt

abbreviate them to a shorter unique name. When no length is specified
