jshell tool: opinions sought -- double-dash long-form command-line options

[Robert Field]

We would like the jshell tool to roll-out using the more modern 
double-dash options.  Note though that it will ship in the jdk/bin 
directory where almost all commands use legacy option formats.

Below I propose options for jshell, as this is not a black-and-white 
decision, I'd very much like input....

Current jshell options are --

     -classpath <path>    Specify where to find user class files
     -cp <path>           Specify where to find user class files
     -startup <file>      One run replacement for the start-up definitions
     -nostartup           Do not run the start-up definitions
     -feedback <mode>     Specify the initial feedback mode. The mode may be
                          predefined (silent, concise, normal, or 
verbose) or
                          previously user-defined
     -q                   Quiet feedback.  Same as: -feedback concise
     -qq                  Really quiet feedback.  Same as: -feedback silent
     -v                   Verbose feedback.  Same as: -feedback verbose
     -J<flag>             Pass <flag> directly to the runtime system.
                          Use one -J for each runtime flag or flag argument
     -R<flag>             Pass <flag> to the remote runtime system.
                          Use one -R for each remote flag or flag argument
     -help                Print this synopsis of standard options
     -version             Version information
     -fullversion         Full Version information

java options are mostly single-dash options, the current double-dash 
options are --

     -cp <class search path of directories and zip/jar files>
     -classpath <class search path of directories and zip/jar files>
     --class-path <class search path of directories and zip/jar files>
                   A : separated list of directories, JAR archives,
                   and ZIP archives to search for class files.
     -p <module path>
     --module-path <module path>...
                   A : separated list of directories, each directory
                   is a directory of modules.
     --upgrade-module-path <module path>...
                   A : separated list of directories, each directory
                   is a directory of modules that replace upgradeable
                   modules in the runtime image
     -m <module>[/<mainclass>]
     --module <modulename>[/<mainclass>]
                   the initial module to resolve, and the name of the 
main class
                   to execute if not specified by the module
     --add-modules <modulename>[,<modulename>...]
                   root modules to resolve in addition to the initial 
module.
                   <modulename> can also be ALL-DEFAULT, ALL-SYSTEM,
                   ALL-MODULE-PATH.
     --limit-modules <modulename>[,<modulename>...]
                   limit the universe of observable modules
     --list-modules [<modulename>[,<modulename>...]]
                   list the observable modules and exit
     --dry-run     create VM but do not execute main method.
                   This --dry-run option may be useful for validating the
                   command-line options such as the module system 
configuration.

Of these, --class-path, --module-path, --add-modules, and maybe 
--upgrade-module-path seem appropriate for jshell.

Proposed for jshell --

     -classpath <path>    Specify where to find user class files
     -cp <path>
     --class-path <path>

     -p <module path>      directory of modules.
     --module-path <module path>...

     --upgrade-module-path <module path>...   directory of modules that 
replace upgradeable modules

     --add-modules <modulename>[,<modulename>...]   root modules to resolve

     --startup <file>      One run replacement for the start-up definitions

     --nostartup           Do not run the start-up definitions
     -n

     --feedback <mode>     Specify the initial feedback mode. The mode 
may be
                          predefined (silent, concise, normal, or 
verbose) or
                          previously user-defined

     -q                   Quiet feedback.  Same as: --feedback concise

     -qq                  Really quiet feedback.  Same as: --feedback silent

     -v                   Verbose feedback.  Same as: --feedback verbose

     -J<flag>             Pass <flag> directly to the runtime system.

     -R<flag>             Pass <flag> to the remote runtime system.
