Paul Benedict commented on LANG-673:
------------------------------------

Curiously, StringUtils has an abbreviate(), which is a different implementation 
than this one. Do we need two versions?

> WordUtils.abbreviate() throws undocumented StringIndexOutOfBoundsException

> The javadoc does not indicate that the string must already be long enough to 
> abbreviate; yet it really does or an Exception is thrown. For example, if you 
> try to abbreviate a string of length 10 at 40 characters, this will fail. I 
> believe this should be allowed... just without any abbreviation.
