conjunct formation should follow input sequence when inserting text

conjunct formation should follow input sequence when inserting text

[Praveen A]

Example to illustrate this bug is അപ്‌ലോഡ് (upload).
>>> a=u'ലോഡ്'
>>> b=u'അപ്'
>>> c=u'അപ്‌ലോഡ്'
>>> print repr(c)
u'\u0d05\u0d2a\u0d4d\u200c\u0d32\u0d4b\u0d21\u0d4d'
>>> d=u'അപ്ലോ‌ഡ്'
>>> print repr(d)
u'\u0d05\u0d2a\u0d4d\u0d32\u0d4b\u200c\u0d21\u0d4d'
>>>

Here ZWNJ is added to prevent formation of conjunct 'pla' (\u0d2a\u0d4d\u0d32).

Enter ലോഡ് (\u0d32\u0d4b\u0d21\u0d4d) first, move cursor to the
beginning of the word, now enter അപ് (\u0d05\u0d2a\u0d4d). Now ZWNJ
entered will not be after 0d4d, but after the conjunct 'plo'
(\u0d2a\u0d4d\u0d32\u0d4b). gedit/pango has the correct behavior,
wherein the ZWNJ is inserted after 0d4d breaking the conjunct 'pla'
(\u0d2a\u0d4d\u0d32) as expected.

Ah, I see your point.  It seems that we must set
disable-point-adjustment to t when a character/string is
inserted in a buffer.  I'll work on it.

I have one question.  Emacs tries hard to find a grapheme
boundary to put cursor on.  For instance, in the above (c)
string, when you put cursor on the second character പ
(U+D2A) and type C-f, the cursor moves to ലോ (U+D32 U+D4B),
and the next C-f moves the cursor to ഡ (U+D21).

But, in gedit, "പ്‌ലോ" is treated as one cluster and you
can't put cursor between "പ്‌" and "ലോ".

Which is convenient for Malayalam user?
