  Changed paths:
    M lldb/include/lldb/Interpreter/CommandObjectMultiword.h
    M lldb/source/Commands/CommandObjectMultiword.cpp
    A lldb/test/Shell/Commands/command-wrong-subcommand-error-msg.test

  Log Message:
  -----------
  [LLDB]Provide clearer error message for invalid commands. (#111891)

Sometimes users (esp. gdb-longtime users) accidentally use GDB syntax,
such as `breakpoint foo`, and they would get an error message from LLDB
saying simply `Invalid command "breakpoint foo"`, which is not very
helpful.

This change provides additional suggestions to help correcting the
mistake.
