Bug in Phobos' process.d: "Executable file not found" is supposed to show executabloe name but fails

[Van de Bugger via Digitalmars-d]

I found a bug in Phobos library, but failed to find a way to 
report it. I do not see "Issues" tab on page 
https://github.com/D-Programming-Language/phobos, so I'll report 
the bug here.

Look at file process.d line ~360, it is the very beginning of 
function spawnProcessImpl:

    const(char)[] name = args[0];
    if (any!isDirSeparator(name))
    {
        if (!isExecutable(name))
            throw new ProcessException(text("Not an executable 
file: ", name));
    }
    else
    {
        name = searchPathFor(name);
        if (name is null)
            throw new ProcessException(text("Executable file not 
found: ", name));
    }

Look at the "else" clause. If function searchPathFor failed, we 
are throwing an error "Executable file not found: ", which is 
supposed to include name of executable file. But name at this 
moment is null... :-(
