Working directory

["Yury Sulsky" <ysulsky hotmail com>]

Hi,

I've found that some applications (such as eclipse - http://www.eclipse.org) 
expect to have their working directory be set to the directory that the 
executable resides in. This behaviour is also good for launching files (e.g. 
if I use nautilus to open ~/music/song.mp3, nautilus should open my mp3 
player with working directory ~/music),  so I've attached a diff that 
attempts to do this.

Warning: I haven't tried to compile this, and I don't know if this is the 
correct way to go about it (in short, I have no clue what I'm doing).

The way it works is it modifies nautilus_launch_application and 
nautilus_launch_application_from_command in 
libnautilus-private/nautilus-program-choosing.c:

nautilus_launch_application prepends a "cd [file's directory]; " to the 
command passed to nautilus_launch_application_from_command, and the latter 
prepends "cd [executable's directory]; " if no arguments were passed to it.

Is this even remotely correct?

Thanks,
Yury
