I doesn't need to be ugly. Why not put the Popen thing in a def
somewhere? Is there any remaining uglyness besides this:

-    return any(url.startswith(i) for i in prefixes)
+    for prefix in prefixes:
+        if url.startswith(prefix):
+            return True
+    return False

Pythonish version:
-    return any(url.startswith(i) for i in prefixes)
+    return True in (url.startswith(i) for i in prefixes)

Note that due to the use of an iterator (which P2.4 has) rather than a
list or set, the expression is just as efficient, i.e. calls
startswith() only as often as necessary.
