+Subject: [PATCH] Cast basic_istream to bool.
+
+This shouldn't be necessary as far as I understand it (istream has an
+operator bool()), but clang 3.4 with libc++ insists that it can't cast
+basic_istream to bool. This may be a bug in libc++ or my bad
+understanding of C++ cast rules, but changing it doesn't hurt.
