Pathname Questions

    (Pardon this if it's been fixed since Excelsior, we don't have anything
    more recent here)

You should go out to your nearest bookstore (that carries Digital Press books)
and buy a few copies before they run out.

    Excelsior defines the pathname merging operation as taking a pathname,
    a defaults pathname, default type, and default version, while the
    merge-pathnames function does not take a default type as an option.
    Is this a mistake?  If not, then how does one specify a default type
    for merging?

These sound like typos; no doubt they're fixed in newer versions.

    Also, *load-pathname-defaults* is supposedly only a single pathname,
    however, it's very convenient to have a list of pathnames to search.
    This is very handy in PSL for loading modules, since you can search
    your own directory, the directory of new hacks, and the standard
    load module directory, in that order.  Does the CL spec preclude using
    a list of pathnames in *load-pathname-defaults*?

See the documentation of REQUIRE.  LOAD is an operation on single files.
