Without the functionality such as that 188.8.131.52 still offered, it is now not possible to use "git-rev-parse --is-inside-work-tree" to detect whether the current location is controlled by a git repository without emitting the "fatal: Not a git repository (or any of the parent directories): .git" error message, when it is not. There is no functional "--quiet" switch, and the usual error/std redirection to /dev/null doesn't seem to work to squelch the output.
If "--is-inside-git-dir" and "--is-inside-work-tree" are indeed not supposed to emit "false" when outside of a git repository, perhaps there is another way I can use (in a bash script) to cleanly detect whether a specific path is part of a git repo or not?
