Posssible Typo in Sigils

[joeltrew]

Under the regular expressions part it says "Because Elixir supports Perl Compatible Regular Expressions (PCRE), we can append i to the end of our sigil to turn on case sensitivity."
however the example shows this turns off case sensitivity, and makes the regular expression insensitive to case
