Fixed with volatile modifier, right?

I'm close to push this patches, but I still doubt in names, and I'd like to see 
comment from English speackers:
1 sml_limit GUC variable (options: similarity_limit, sml_threshold)
2 subword_similarity(). Actually, it finds most similar word (not substring!) 
from whole string. word_similarity? word_in_string_similarity?


substring_similarity_pos() could be a separate patch.
