If there is a tie, return a sorted list of all extensions.

Hi,

• hex-1,4-diene, right, sorry about that.
• tridec-4,10-"dien"-2,6,8-triyne: this one is on prupose. the additionnal e is only a "rule" about making the name more easy to pronounce. As I state it in the last section, I don't handle such a type of thing. There are already far enough things to do without it.
• en/ene: same thing
• "di ene yl undec -> nope, never an additional e before another vowel (at least.... not in french version?). But anyway, see above.
• you can see an example of input and output at the very top of the description (I know, one totally forgets there were things there once one reads the next parts... x) )

cheers
