Verses are made up of words and words are made up of symbols.  So the 
order should be "symbols words verses", not "symbols verses words".

Oh, you meant "vers_u_s" not "vers_e_s".  OK.  I'll shut up now.

For example, if I'm writing C code and I want to find foo but not foo_bar, I usually do \<foo\>  but really it seems that I should be doing \_<foo\_>  ... fine.  I can make that adjustment.  But when I do incremental search, I often hit ^w to pull in the next word but what I really want (often but not always) is to pull in the next symbol (into the search string).  So if I'm sitting at this_that, I'd ilke to hit ^W (perhaps) and pull in this_that instead of just this.
