Subject: command: avoid going through prop->opt bridge from opt->prop bridge

The option->property bridge can't (and shouldn't) preserve option flags.
This is a problem if the flags are actually used by the option
implementation, beyond calling m_config_mark_co_flags().

This was true so far, but b8193e40719 changed this. Now setting the
--profile option (usually from a config file or as recursive profile)
can have side-effects that depend on the flags contents. Solve this by
avoiding going through the "double bridge" altogether.

This fixes a regression if an auto-profile is active, and the user
specifies an option on the command line that is supposed to override an
item in a profile recursively referenced by the auto-profile. The
command line option will not override it, because the auto-profile is
set later, and during application of the auto-profile, the
M_SETOPT_PRESERVE_CMDLINE flag gets lost.

Having to add something to m_property is not nice, and I'll probbaly
regret later. On the other hand, there is a chance that this helps
towards true option/property unification.
