[XeTeX] avagraha+anusvara ligature in devanagari

[Yves Codet]

I know this rule :) But avagraha doesn't stand for any sound, it only  
marks elision (or contraction) and can be omitted, that's why it can't  
bear anuswâra, which would explain why fonts don't have any rule to  
place an anuswâra over an avagraha. If you have John Smith's  
electronic edition of the Mahâbhârata, you will easily find several  
occurences of the particular case you're dealing with, for instance:

01058049a अथ ते सर्वशोंऽशैः  
स्वैर्गन्तुं भूमिं  
कृतक्षणाः
