[Orgmode] BUG: State change eats headings beginning with "Read" or "Reading"

[Manish]

Curiously state change causes the headings beginning with "Read" or "Reading
to be chopped of those words.  Example below.

--8<---------------cut here---------------start------------->8---
# test file
* Reading/RSS
  This heading becomes"/RSS" after S-right.
* Read/RSS
  This heading also becomes "/RSS" after S-right.
* Read RSS
  This heading becomes "RSS" after S-right.
* Readingx/RSS
  This heading behaves correctly with S-right.
* Readingx RSS
  This heading behaves correctly with S-right.
* Rea/RSS
  This heading behaves correctly with S-right.
* Rea RSS
  This heading behaves correctly with S-right.
* RSS/Reading
  This heading behaves correctly with S-right.
* RSS Read
  This heading behaves correctly with S-right.
* Readx RSS
  This heading behaves correctly with S-right.
* Tread carefully
  This heading behaves correctly with S-right.
--8<---------------cut here---------------end--------------->8---

Thanks

PS: Does anyone know how to stop Emacs 23 from prefixing every line of a
paragraph (after the first one) with tabs in message mode?  It seems to work
okay in other modes.
