std.process.execute without capturing stderr?

[berni]

I need to execute a program and capture stdout, which I hoped 
std.process.execute would do. But unfortunatly this command also 
captures stderr, which I need to be ignored. When looking at the 
implementation of std.process.execute I see, that I can probably 
do this by removing "Redirect.stderrToStdout" in the function 
executeImpl. But for that I have to copy lots of functions from 
phobos in my own code. Is there an easier way to do that?

In case you wonder why I need this: I'm currently using a PHP 
frontend and a D backend. I'm calling the D routines with the PHP 
exec command which works fine, but unfortunately removes trailing 
whitespaces, that I need. Therefore I'd like to have a wrapper 
that replaces all whitespace by some escape sequences which than 
are restored in PHP. First I thought I can use sed for that, but 
unfortunately the return code gets lost here. I'm using stderr to 
show some progress information, which should be shown 
immediately. (I've you've got other ideas how to get arround this 
design flaw (as I see it) in php exec, I'd be happy too.)

I don't want to touch the D backend - that's not the place, where 
the problem lies and when I decide to change the frontend I've to 
remember to change the backend too, which I don't like.

Here my complete program:

> import std.process;
> import std.stdio;
> import std.array;
> 
> int main(string[] args)
> {
>     const result = execute(args[1..$]);
>     writeln(result[1].replace("\\","\\\\").replace(" ","\\s"));
>     return result[0];
> }
