mailcap files may contain entries with a specific MIME type
(e.g., text/plain) or with a MIME type that uses a wildcard
for the subtype (e.g., text/*). MailcapCommandMap will search
mailcap files in order, first looking for an exact match in each
mailcap file, followed by a wildcard match in that same mailcap
file, before moving on to the next mailcap file in the search
list.

In some cases it's desirable to include both entries for specific
MIME types as well as an entry with a wildcard to allow support
for types that don't have more specific support. However, because
of the current search rules, and the inability to control the
order of searching in some cases (e.g., the java.ext.dirs directory),
The wildcard entry in one mailcap file may be found before the
specific entry in another mailcap file.

This is particularly a problem with JavaMail, which would like to
provide support for many MIME types in a rather generic manner,
without preventing applications from providing support that is
more precisely matched to the particular MIME type.

There should be a way to mark entries, in particular wildcard
entries, so that they will only be used if a more specific match
is not found after searching all mailcap files.
