Help text and man page mention non-existent --ignore-nothing option

[cpick]

I'm running macOS Ventura.

The help text (and man page) mention an --ignore-nothing option:

$ watchexec --help | rg -- --ignore-nothing
          '--ignore-nothing', the write events to the log will likely get picked up by Watchexec,

But that doesn't exist:

$ watchexec --ignore-nothing 2>&1 | head -1
error: unexpected argument '--ignore-nothing' found

I'm running the following version (installed via Nix):

$ watchexec --version
watchexec 1.22.2 (1980-01-01)
build-date: 1980-01-01
