thai-word.el minor bug report

[Poonlap Veerathanabutr <poonlapv@gmail.com>]

Hello Werner,

I am testing thai-word.el features from CVS and I think I found minor 
which is not a big deal.

My emacs was compiled from CVS with --with-x-toolkit=gtk. Here is the 
process to see the case.

- Run emacs in environment LANG=th_TH.TIS-620
- In *scratch* buffer, write a Thai sentence without space, no white 
space or newline at the end of line.
- If I try M-b or something related to Thai word, I will get "Wrong type 
argument: integerp, nil" in mini-buffer. And cursor will jump to the 
begining of line. Please note that there is no space in the line.
- If I have white space or newline at the end of file, there is no 
problem at all.


Thank you,

Poonlap
