    No.

Yes, I think.  child_setup in callproc.c has code to do that.

Emacs's own current directory (at the system level) doesn't normally
matter, because Emacs does its own computations to produce absolute
file names.  The only time it would matter is when another process
is supposed to inherit it; and that, Emacs does manually (in child_setup,
for instance).
