л{й}я = н{й}я

[hectoralos]

In words finishing in н{й}я й is substituted by ь before ӑ. This is correct. The same should happen for words finishing in л{й}я. For instance:

$ echo "Коля<np><ant><m><ins>" | hfst-lookup .deps/chv.LR.lexc.hfst 2>/dev/null
Коля<np><ant><m><ins>	Кол{й}я>п{A}	0,000000

Generates Колйӑпа instead of Кольӑпа.

$ echo "Коля<np><ant><m><ins>" | hfst-lookup .deps/chv.LR.hfst 
Коля<np><ant><m><ins>	Кольӑпа	0,000000

Should be fixed in 23fbb91 .

For the record, I have seen that the change is general. This almost relates to Russian personal names like Катя, Настя, Вася, etc. There very few words like сакля, to which to rule applies.
