At least on Linux both calls are equal. Be careful with fstatat() and
make the flags field 0, the flag value AT_SYMLINK_NOFOLLOW will make
it equal to lstat().
IMO it would be a good idea to replace all calls to stat(".",&sb) with
fstat() calls within the shell (which already keeps track of the
current cwd with shp->pwfd) to make such calls faster. stat() always
includes a path lookup and permission checks which fstat() doesn't
have to do.
