[kaffe] bug: jar -t/-x does't handle paths correctly

[Kurt Miller]

When jar is passed a path as a parameter using -t or -x, it
doesn't recurse into the directory and list/extract the files and
directories under it.

For example: given a test jar that looks like this:
$ jar tf test.jar
META-INF/
META-INF/MANIFEST.MF
com/
com/intricatesoft/
com/intricatesoft/test.class

$ jar tf test.jar com

lists nothing. jar xf com extracts nothing too.

This is with 1.1.5. I have tried 1.1.5 with
libraries/javalib/kaffe/tools/jar/Jar.java patched to match the
HEAD version too.
