Hello Cygwin Team,

My request is related to an issue I opened in the FLAC Github :
https://github.com/xiph/flac/issues/861

After some investigations, the issue is related to the build release of the
FLAC package provided by Cygwin : the man pages of flac(1) and metaflac(1)
use the HYPHEN (U+2010 )  character instead of the HYPHEN-MINUS  (U+002D)
character.

These two commands expect HYPHEN-MINUS character, so if you copy-paste the
man page options in your terminal, it will fail.

Example : flac ‐‐version
will return an error : « can't open input file ‐‐version: No such file or
directory », because of  « ‐‐version » with HYPHEN copied-pasted from the
man pages.

The right string is « --version » with HYPHEN-MINUS (U+002D).

Example : flac --version
will return : « flac 1.5.0 »

Please, feel free to read the issue in Github (
https://github.com/xiph/flac/issues/861 ) for more details, as it's easier
to read code and quotes with the markdown formatting.

This is a very pretty nasty kind of bug, because it's very difficult to
distinguish HYPHEN-MINUS and HYPHEN in a terminal. It's also very difficult
to figure out why the command has failed, as the « No such file or
directory » is not the root cause of the problem.

I think a new build release to fix this, would be very welcome.

Thank you very much for your time and your great work. :)

Kind regards,

Vyncere.
