1516	command-line breaks when a command is a prefix of another command (was: make install: '_Defer' object has no attribute 'function')	Tristan Croll	Greg Couch	"I *think* this has been triggered because I defined a set of commands `clipper xxx ...` for which the existing `clip` command is a prefix. Anyway, when I run `make app-install` I get, at the tail end of the build:

{{{
Executing: toolshed install './dist/ChimeraX_Clipper-0.2.1-cp36-cp36m-linux_x86_64.whl'
unloading module chimerax.clipper

exit
Unknown command: exit

}}}

With no traceback I have no idea where the offending `_Defer.function` call is (I believe it should be replaced with `...proxy`), but adding the following to `commands.cli._Defer` is a successful band-aid:

{{{
    @property
    def function(self):
        return self.proxy
