This could also just be:

    char *git_dir = xstrdup(absolute_path(...));

with a corresponding 'free(git_dir)' below.

Similarly, it looks like 'path' doesn't need to be a strbuf at all
since the result of absolute_path() should remain valid long enough
for fspathcmp(). It could just be:

    const char *path = absolute_path(...);
    wt->is_current = !fspathcmp(git_dir, path);

But these are very minor; probably not worth a re-roll.
