Subject: [boost] [program_options] empty string argument
From: Benedek Thaler (thalerbenedek_at_[hidden])

I have the exact same problem:

--compression '' gave me a specified, empty compression switch value, as
expected, on boost 1.58.

However, on 1.59, the empty string counts against the positional arguments,
and causes regressions.

Also, --compression='' gives:

The argument for option '--compression' should follow immediately after the
equal sign.

What is the recommended workaround? Is it planned to be fixed/changed?
