scala 3 repl does not work with -cp argument, needs -repl as workaround

See original GitHub issue

Compiler version

3.0.0 and 3.0.1-RC2

Minimized code and output

The repl cannot be started with a -cp argument.

In 3.0.0 using the .zip from the release on Ubuntu:

$ scala -cp "some.jar" 
warning: command option is not correct.

In 3.0.1-RC2 instead of a warning, the -help output is printed.

Expectation

Should start the repl with “some.jar” on claspath.
Should work as in Scala 2.

Undocumented workaround:

$ scala -cp "some.jar" -repl

When might stable 3.1.0 earliest be out on github releases?

If no issues are found with the 3.1.0-RC1 releasing about September 1 then the 3.1.0 final should be about October 13th

Great! (I have just added a note in my teaching material that -repl in conjunction with -cp is not needed from Scala 3.1.0. It will be sent to print on sunday…)
