I'd prefer just a single, unconditional call here:

		probe_utf8_pathname_composition(path, len);

with something like this at the top of the file:

	#ifndef PRECOMPOSED_UNICODE
	#define probe_utf8_pathname_composition(a,b) /* nothing */
        #else
        void probe_utf8_pathname_composition(char *, int);
	#endif

and implementation of the function body in compat/darwin.c (Didn't I see a
comment on the name of this file, by the way? What was the conclusion of
the discussion?).

Style.

Hmmmmm.  Is it safe to call git_config() this early in the program?  Have
we determined if we are in a git managed repository and where its $GIT_DIR
is?
