It is strange. There's nothing related to the problem committed to
4-stable after 4.3-release (according to the cvsweb on www.freebsd.org).

At this moment, the globbing feature does almost nothing that the
globbing itself was intended for; it just returns the `550 ambiguous'
error when more than one entry match the glob pattern, e.g. CWD /*.
After all, a single RETR/STOR/CWD command is designed to be used on a
single file or directory. IMO the globbing can be thought as nothing
other than a convenient shorthand (i.e. we can do /usr/src/sbin/merge*),
and if it is the only reason I'd say we move the globbing feature
entirely to the client side.
And actually the globbing is done at the yacc level so *all* on-the-wire
pathnames are subject to globbing (see the pathstring-to-pathname
production in ftpcmd.y), which is just gross.
