Now this starts to break "-o" option when the command is run from a
subdirectory of a git working tree, I suspect.

The setup() will discover that you are in a Git controlled working
tree, goes up to the top-level of the working tree, so a user may
expect

	cd t && git bugreport -o frotz

to create a new directory t/frotz, but it would instead create the
directory frotz next to t/, no?

Using OPT_FILENAME and feeding correct prefix to parse_options()
will correct this.
