  Add check if we need to precompose unicode on Mac This adds initialization of core.precomposeunicode to repo init on Mac. This is necessary because when a Mac accesses a repo on a VFAT or SAMBA file system, it will return directory entries in decomposed unicode even if the filesystem entry is precomposed. This also removes caching of a number of repo properties from the repo init pipeline because these are properties of the specific filesystem on which the repo is created, not of the system as a whole.
