13085	Bad command line escaping for Windows shell	Salamandar <felix@…>		"I'm trying to launch a command with the windows shell:

{{{
#!bash
call ""%VS140COMNTOOLS%\vsvars32.bat""
}}}
so the source is: (i have to escape the double-quotes and antislash)
{{{
#!c++
std::string getCommandLine() {
  return ""call \""%VS140COMNTOOLS%\\vsvars32.bat\""""
}
bp::child child(getCommandLine(), bp::shell);
}}}

The problem is that Boost is double-escaping the double-quotes, and the windows shell does not understand that:
{{{
Error: '\""C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\\vsvars32.bat\""' is not recognized as an internal or external command, operable program or batch file.

The problem resides here :
boost/process/detail/windows/basic_cmd.hpp :35 :48 :72

I just had to comment these lines to fix the command line and spawn the shell with the correct args.
