Fix incorrect backslash escaping of `\\`
The regular expression part `\\` must be written as `\\\\`, not `\\\` in
a PHP string variable. Although both variants (`\\\\` and `\\\`) will be
passed as `\` to the regex engine in this specific case, it's correct to
use 4 backslashes, as the PHP manual tells you:
