in the boundary detection

1.5.3: 2010-09-05 09:26 UTC

Major Bugfix release.

Apart from a major cleanout of the bug tracker for this package, this
release includes a revamped parseHeaderValue which removes the rather
flakey regex, with a real parser, which should be considerably more
robust.

         list each() .. this is 2010 ;)...
#11410 - support wap multipart

        etc.. aaa*0=.... aaa*1=.... aaa*2=.... (merged into aaa=.....)
