Our fmath_test (a.k.a. unit_fmath) test was failing with an exception thrown by the fmt library because we used a width specifier when formatting a TypeDesc.
It was really only an issue when using old fmt < 10.0, so I'm just solving it trivially by ignoring that specifier for old fmt. It doesn't seem necessary to make it work correctly with width specifiers for old versions, when we don't in any way rely on it.
