Language specific subcommands may be used directly (without the `language
<language-name>` prefix), when stopped on a frame written in that language. For
example, from a C++ frame, users may run `demangle` directly, instead of
`language cplusplus demangle`.

Language specific subcommands are only available when the command name cannot be
misinterpreted. Take the `demangle` command for example, if a Python command
named `demangle-tree` were loaded, then the invocation `demangle` would run
`demangle-tree`, not `language cplusplus demangle`.
