 Review comment:
   I am starting to wonder if `len` would be better named `lengthHint` to make 
it clearer that this length is not a guarantee in any shape or form of the 
length of the returned string.

> In some cases, the algorithm decides incorrectly when to which package names 
> to abbreviate. For example, abbreviating
> {{org.apache.commons.lang3.ClassUtils}} to the length 18 will result 
> {{o.a.c.lang3.ClassUtils}} (22 characters) instead of {{o.a.c.l.ClassUtils}} 
> (18 characters as requested). The reason for this is that the algorithm 
> starts from the right and goes to the left abbreviating the packages and 
> starts to abbreviate the packages when it runs out of the available space.
> Instead, the algorithm should start from the left and abbreviate all packages 
> that would result in a too-long string without abbreviating the package name.
