RE: [lang] How should StringUtils.indexOfAny handle "" in search string?

[Gary Gregory <gg...@seagullsw.com>]

The convention could perhaps also bracket template like things with
<i>template</i>, as in:

/**
  * Blah Blah <code>Foo.bar(<i>inputValue</i>);</code> Blah Blah.
  */

I guess it has to be. String.indexOf("") returns 0. So this just matches
that behaviour.

I think I'm OK with it. The downside is it involves learning a convention.
But I think its probably obvious enough. Any other views?
