[EDIT BY danbrown AT php DOT net: The following
is a bugfix provided by (gardan AT gmx DOT de)
on 31-MAR-2005 with the following note:
"This means: $length should not be even,
but divisible by 4. The reason is that in
base64-encoding 3 8-bit-chars are represented
by 4 6-bit-chars. These 4 chars must not be
split between two encoded words, according
to RFC-2047.
*/

// with spacers after each chunk

// remove trailing spacer and
// add start and end delimiters
