That's good, but it's a little long and hard to read.

Okay, here goes....  This is untested, obviously....

  WSPC=" ^I" # you-know
  NL="
"
  :0 B
  * 1^1   ^Content-Type:
  { PARTS=$= }

  :0
  * ! PARTS ?? ^^[01]^^
  *     ^Content-Type: multipart/.*boundary="\/[^"]+
  * $ B ^--$MATCH${NL}(\
         
Content-Type:[${WSPC}]+text/plain;?([${WSPC}${NL}]+charset=${DQ}.+${DQ})${NL}|\
         Content-Transfer-Encoding:[${WSPC}]+.+${NL})+\
         ()[${WSPC}${NL}]+
        ^--$MATCH{NL}
  { W="empty text/plain block" }

Does that look like it'll work?  What's it missing?
