Properly handle commits like:
commit f2791e7eadf4 ("Revert "floppy: refactor open() flags handling"")

Try this one:

https://lore.kernel.org/lkml/7f55d9d0369f1ea840fab83eeb77f9f3601fee41.camel@perches.com/ (local)

It works but why not to use .+? then?
I'm not sure that non-greedy patterns will properly handle commits like:
$ git log --oneline | fgrep '")'

e.g. 
commit ece2619fe8ed ("extcon: arizona: Fix flags parameter to the gpiod_get("wlf,micd-pol") call")
