This plugin converts existing filenames that were stored using the
option "safe" in fnencode from using the dot (.) as post_indicator to
using a bracket (]) as post_insdicator. It will also add a
post_indicator at the end of the file name should it be missing (Bug
FS#2122).

This plugin needs testing by people using the safe encode option!

Note, any filenames encoded with the previous SafeFN scheme will need to
be converted to the new scheme.  Users of the old SafeFN scheme should
not use this new scheme until after converting their filenames.

Before this patch with a .htaccess file on a higher level in the
hierarchy with "Satisfy Any" it has been possible that the directory
protection didn't work as expected.
