--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
N.B. test_summary doesn't print that "[master r14-3825-g0d50fac]" string
itself, it just scrapes it from the logs, and the string in the logs comes
straight from the xgcc. xg++ etc. binaries.

I don't think it's the test_summary script's job to correct bad info in the
logs.
