Instead of having files foo.html "in front of" foo/, I prefer to have foo/index.html. This patch allows that. Specifically, foo/index.type is translated to $links{'foo/'}, and bestlink looks for either "foo" or "foo/" when linking to pages. There are other miscellaneous changes that go with that -- parentlinks for "foo/" are the same as for "foo", except one directory higher; basename of "foo/" is "foo"; links to "foo/" are translated to "foo/index.html" rather than "foo/.html". (Links to "foo/" might be preferred, but that causes an infinite loop in writefile, because apparently dirname("foo/") == "foo/" on my system for reasons that aren't clear to me.)
