[boost] [string algo] again strange split behaviour

hi,

I assume the behaviour of boost::split not to return the last token has 
been changed (in CVS). However, a side effect seems to be that there is 
also one token returned for _empty_ strings, which is very questionable IMO!

summary (if '/' is the separator):

boost 1.32:
""              -> 0 tokens
"abc/abc"       -> 2 tokens
"abc/abc/"      -> 2 tokens

CVS:
""              -> 1 token (!)
"abc/abc"       -> 2 tokens
"abc/abc/"      -> 3 tokens

should be IMO:
""              -> 0 tokens
"abc/abc"       -> 2 tokens
"abc/abc/"      -> 3 tokens

Thoughts?

Stefan
