The actual working directory as seen by the kernel/process should indeed =
be irrelevant. What matters is that when processing command-line =
arguments in batch mode, Emacs behaves like other Unix tools in that it =
resolves relative filenames as relative to the working directory that =
was current when the process was started. In other words, when =
executing
emacs -Q -batch -eval '(print default-directory)'
from a shell, Emacs must always print a representation of the shell's =
current working directory (ignoring corner cases such as "default =
directory has been removed during process startup"). Guaranteeing that =
(a) when processing command-line arguments the *scratch* buffer is =
current (unless changed by a previous command-line argument), and (b) =
its default directory will be set to a representation of the initial =
process working directory should ensure that. I guess that's already =
the case for all operating systems, and we only need to document it.=
