bug #12620 (UTF-8 indexing causes ER_NO_KEYFILE error)
The problem is that on some Mac OS X-es the file writing/reading
call with zero bytes to read/write returns error.
So here i try to eliminate that kinds of calls.
myisam/mi_check.c:
zero length copying avoided
mysys/my_chsize.c:
no file operations if it's not necessary
