Oh, lol. For the longest time it was like that (since the days of WET 2.0 on IRCan), so I had figured the "c" was intentional.

I'll send over a PR to change it back shortly.

Probably won't happen until sometime tonight, though. I believe it impacts master (v3.1), v4.0, and all the theme repos, so it's not exactly something that'll take like half a second to implement... :(.
