[boost] [program_options] empty string argument

Hi,

I have the exact same problem:
http://boost.2283326.n4.nabble.com/ProgramOptions-explicit-empty-string-argument-td4671813.html

--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?

Thanks,
Benedek
