[MiNT] XaAES: Bug in shel_write?

[Philipp Donzé <philipp.donze@epfl.ch>]

Hi,

While debugging a little GEMJing demo application I realized that
	shel_write(SWM_LAUNCH, GEMAPP, CL_PARSE, path, arg)
has an odd behaviour under current XaAES version:
It changes the current working directory of the parent process to point 
to the directory of the launched child process.
I don't think this behaviour is documented somewhere. (Tell me if I'm 
wrong.)

At the moment I can't test with other AES replacements, as I've only 
MagiC and XaAES installed.

regards
Philipp
