test-context: conditionalize the workingfilectx date printing for Windows
Starting with
13272104bb07, the output changed on Windows:
--- e:/Projects/hg/tests/test-context.py.out
+++ e:/Projects/hg/tests/test-context.py.err
@@ -1,4 +1,4 @@
-workingfilectx.date = (1000, 0)
+workingfilectx.date = (1000L, 0)
ASCII : Gr?ezi!
Latin-1 : Grⁿezi!
UTF-8 : Gr├╝ezi!
Since int and long are both 32 bit on Windows, this seems harmless in practice
other than the previous test failure.
