While I'm here, get rid of (now useless) MCLISREFERENCED and use MEXT_IS_REF

Browse Source 
instead.
Also, fix a small set of "avail." If we're setting `avail,' we shouldn't
be re-checking whether m_flags is M_EXT, because we know that it is, as if
it wasn't, we would have already returned several lines above.
