-  * "refresh" does not calculate a new sha1 file or bring the
-  * cache up-to-date for mode/content changes. But what it
-  * _does_ do is to "re-match" the stat information of a file
-  * with the cache, so that you can refresh the cache for a
-  * file that hasn't been changed but where the stat entry is
-  * out of date.
 - * We fundamentally don't like some paths: we don't want
 - * dot or dot-dot anywhere, and for obvious reasons don't
 - * want to recurse into ".git" either.
-- *
-  * For example, you'd want to do this after doing a "git-read-tree",
-  * to link up the stat cache details with the proper files.
 - * Also, we don't want double slashes or slashes at the
 - * end that can make pathnames ambiguous.
