:-D Yes, you caught me!
These patches *may* not be necessary, prior to Michael's
"reference related races" series. Specifically, the introduction
of the stat_validity_check() function to the reference handling API.
This means that the behaviour 'git show-ref' is now affected by
several config variables, including core.checkstat. I haven't
spent any time auditing the code, but the list would include
(at least) core.trustctime, core.filemode, core.checkstat,
core.ignorecygwinfstricks, ...

Yes, I will send a v2 (soon-ish, I hope).
