I now tried this on Windows 8.1, where the (default) Courier New font
does have a glyph for u+0337, and I see there the same problem as
reported by the OP, including the composition data that shows positive
offsets where I thought negative offsets should be.
Maybe this is something related to the fact that bot DejaVu Sans Mono
and Courier New are monospaced fonts, whereas Arial Unicode MS isn't?
I Hope Handa-san will provide some insight.
