19* Patch by Kai-Uwe Blöm, 12 Mar 2003:
20 Cleanup & bug fixes for JFFS2 code:

23 - the length calculation for files was wrong, sometimes resulting
24 in short file reads.
25 - data copying now optionally takes fragment version numbers into
26 account, to avoid copying from older data.
27 See doc/README.JFFS2 for details.
