The version string at the time:

FreeBSD 13.0-CURRENT #75 main-c572-g82397d791: Sun JanĀ  3 20:00:09 GMT 2021

<https://cgit.freebsd.org/src/log/?qt=range&q=g82397d791> finds nothing.

<https://cgit.freebsd.org/src/log/?ofs=15763> currently takes me to 
around 2021-01-03, with 
<https://cgit.freebsd.org/src/commit/?id=c98a764c681f8b70812a9f13a6e61c96aa1a69d2> 
the first on the 3rd.

Should I assume that it will be impossible, or unreasonably difficult, 
to identify, in cgit, the exact commit that related to g82397d791?

(I know, it was not long after the transition to Git.)

TIA
