I don't claim to be anywhere near an expert on this, but FWIW before
submitting the patch, I checked these:

http://www.oxforddictionaries.com/definition/english/target ("British
& World English")
http://www.oxforddictionaries.com/definition/american_english/target
("American English")

Both of them say "Do not double the final consonant when adding
endings which begin with a vowel to a word which ends in a vowel plus
a consonant, if the stress is not at the end of the word: (targets,
targeting, targeted)."
