When passing in source filenames (rather than package names) on the command
line, the generated web pages do not contain a list of packages, a package page,
or package.html. This request is to include this information, the same as if
the user had passed in a list of package names. Only the specified classes
would be documented with their own class pages -- unspecified classes would
not be documented.

For example, say class C belongs to package p, and C.java is passed in with
"javadoc C.java". Package p and class p.C would be documented.
Unspecified classes that belong to package p would remain undocumented.
