Patch: insight --args -vs- pwd

[Tom Tromey <tromey at redhat dot com>]

I've been using `gdb --args' for quite a while now.
Lately I've come to realize that if I run gdb in this mode, I really
want Insight to ignore the session's notion of pwd and instead use the
directory where I launched gdb.
This makes sense because in `--args' mode you are expecting the
inferior to be run in the "current environment".  Several times now
I've been confused by the current behavior of overriding the pwd with
the session's pwd.

This patch implements what I'd prefer.
Ok to commit?
