Other breakage had accumulated among Settings. I determined
that once upon a time, "MultiStringSetting" accepted arguments
like this:
scala -foo bip bop bar
Somewhere this was changed to force a : argument, like
scala -foo:bip,bop,bar
This incurs breakage. The repl has always advertised its -i
option without a colon and it has always been a MultiStringSetting.
Forcing everything into the : seemed like the wrong thing,
especially because it will stomp on any whitespace containing
arguments, whereas in the original form
scala -foo bip "bop bar" baz
will yield its arguments as given.
So lacking any good ideas and knowing something probably depends
on each way already, I made it work both ways.
