Subject [jira] Created: (LANG-269) Shouldn't Commons Lang's StringUtils have a "common" string method?

Shouldn't Commons Lang's StringUtils have a "common" string method?
-------------------------------------------------------------------

         Key: LANG-269
         URL: http://issues.apache.org/jira/browse/LANG-269
     Project: Commons Lang
        Type: New Feature

 Environment: generic
    Reporter: Michael Dang


A method which accepts a string array and returns a string which is the common portion of
all the strings starting from the left, or more general form of that.

This is very common operation.  For example, one may want to find the common directory of
a set of path strings.

passing in:

"/foo/f1.txt"
"/foo/moo/f2.txt"
"/foo/moo/f3.txt"

should returns "/foo/"

It is tedious to implement this in every project.  And I think Commons Lang StringUtils should
have some methods to help in this.
