Rendering Fix progresses, Now Input-Method (Was:Re: Making the malayalam rendering proper)

[Shyam | ശ്യാം ക ാരനാട്ട് | Karanattu]

Hi sir,
   Its A REALLY GREAT PLEASURE! to read  this blog from suresh ji
   http://suruma.freeflux.net/blog/archive/2008/10/15/emacs-malayalam.html 
   which says about the malayalam rendering in emacs became perfect!
   GREAT THANKS for the work!
   I have tried the same and it seems working perfect so far.
   Now comes  the next wish ;-) to make the malayalam-inscript input method
   perfect. It cant enter zwj and zwnj at the moment. I could
   correct it with a simple (quail-defrule "]" "‍") and (quail-defrule "\\"
   "‌")
   . But i dont know how to specify that in leim/quail/indian.el to
   include it to the default setting. Also the input method contradicts
   with the xkb input layout, as it  swaps the place of two
   characters. i.e emacs' malayalam-inscript layout has z for േ and s
   for െ and Z for  ഏ  and S for എ while its z:െ s:േ Z:എ S:ഏ for xkb
   layout which i cleared by creating another inscript-ml-keytable by
   copying inscript-dev-keytable in the leim/quail/indian.el and swapping the 
place of (?Z ?z) and
   (?S ?s) 
   Its a great joy to get the emacs' own input method than xkb's as the
   control characters work without changing the input method. Otherwise,
   I have to change the input method to do every C-a or C-e ;-) 

   Moreover  I got emacs crashing for various key combinations which
   happens for  both type of input methods(xkb's and emacs').

  (gdb) run
  Starting program: /home/shyam/emacs/src/emacs 
  [Thread debugging using libthread_db enabled]
  [New Thread 0xb7062720 (LWP 17362)]

  [Switching to Thread 0xb7062720 (LWP 17362)]
  0xb7efa410 in __kernel_vsyscall ()
  (gdb) 
 
Thats the message i get as i try to display all the characters by
passing finger over my qwerty keyboard (ACER aspire 5570z laptop) one after the 
other, starting
from the one having `/~ (ൊ/ഒ) and works fine till =/+(ൃ/ഋ) but the next
character q/Q(ൌ/ഔ) makes it break. with the message FATAL Error:(6)
Aborted
but just entering =/+ and q/Q didn't caused crashing. I could also find
some similar keysequence causing the emacs to crash.
