[Snowball-discuss] porter2 question

[Martin Porter]

Wendy,

You have spotted an error! 'b' should not be in the valid_LI list, and I
have now removed it. (See the updated page on the snowball website.) 

This does not affect the working of the Snowball program however: the
'among' expression goes for the longest string, so 'bli' was overriding 'li'
when 'li' was preceded a 'b'. In other word, 'b' in the valid-LI list was
redundant.

Thank you for your help,

Martin
