Per:
fsmonitor-ipc.h- * Returns the pathname to the IPC named pipe or Unix domain socket
fsmonitor-ipc.h- * where a `git-fsmonitor--daemon` process will listen. This is a
fsmonitor-ipc.h- * per-worktree value.

But here we (from eyeballing this, maybe I've missed something):
1. Get the path to the git dir
2. SHA-1 hash that path, presumably to make it fixed size & get rid of
slashes etc.
3. Make that the IPC filename
Per the "per worktree" can't we just check if:
* We have a .git/worktree/? If so derive the name from that.
* We don't? Then we just have one? Stick it in in there? I.e. isn't the
hash_to_hex() here redundant?
...
> + strbuf_addf(&ipc_file, "~/.git-fsmonitor-%s", hash_to_hex(hash));
... but not here, so is it just for this "else", but got carried over
above?
I think if we're creating a new global cookie file, and presumably
potentially a *lot* of them in the user's ~ we should at least
prominently document that somewhere.
But more generally couldn't this?:
* Play nice with $HOME/.config/git/ etc, as is the usual convention these days on *nix
* We would have to the equivalent of a "mkdir -p", but if we stick it
in .config/git/fsmonitor-sockets or something we could have a nested
path there that mirrors the path to the repo.
The latter can really help with debugging, you have this random
.git-fsmonitor-XXXXX file, where the XXXX is totally mysterious, until
you eventually find this code & discover it's a SHA-1 hash of some other
path...
