Re: [PATCH v2 1/1] macOS: ls-files path fails if path of workdir is NFD

tboegi@web.de writes:

Looks good. I've queued with a slight rewording to the proposed log message, and a bit of extra quoting in the test. Any string that contains "$aumlcdiar" are enclosed in a pair of double-quotes in the script, so not just the one given to ls-files, other two references to it are also quoted now.

Thanks.
