The current behavior strips leading dashes from un-recognized options.

Input                  = -foo -ro  mapall test_host test-host
current output         =  foo -ro -mapall test_host test host
w/patch in bug #168158 =  foo -ro -mapall test_host test-host
w/patch in bug #176449 = -foo -ro -mapall test_host test-host

So the other patch is minimal change (only fixes preserving dashes inside host
names) while the patch here also passes unrecognized options with leading
dashes.

Not sure which is preferred in this case; stripping the dash is likely not
optimal from a security point of view, as -foo becomes the hostname foo...
Should it perhaps remove strings that look like options but aren't recognized?
Or pass them as (invalid) arguments into exports?
