+rTorrent sometimes creates invalid torrents which has empty path components.
+the bitorrent spec allows for "" strings, but they make no sense in paths.
+so instead of always adding a / in between, skip them. ugh.
+
+for example:
+dict {
+ 'info' => dict {
+ 'name' => str = "some dir" (len = 8)
+ 'files' => list [
+ dict {
+ 'length' => int = 12345567
+ 'path' => list [
+ str = "" (len = 0)
+ str = "foo.bin" (len = 7)
+ ]
+ }
+ ...
+ ]
+ ...
+ }
+ ...
+}
+
+ctorrent will then try to fetch the file "/some dir/foo.bin" instead of
+"some dir/foo.bin" (relative to $PWD).
