Henri Yandell updated LANG-687:
-------------------------------

    Description: 
Wherever possible, use CharSequence and not String in the StringUtils API.

Here is the working list of methods that don't take CharSequence. I'll update 
the description in place to show status.

  was:
Wherever possible, use CharSequence and not String in the StringUtils API.

substring can go to subSequence inside code. The general substring method can 
be replaced with a subSequence method and substring deprecated(?). One question 
is whether to implement a CharSequence.indexOf type method. Given that it's 
merely a walking method(?!?), this might be quite handy and would allow a bunch 
of StringUtils methods to move over.
