Yes, it would.
In all of the *-generic.conf config files, $DATA is surrounded by single
quotes.  The current version of generic.c escapes ", `, and \, but not
'.  The three characters `, \, and " don't even need to be escaped in a
single-quoted string, since they are interpreted literally.  There's no
way to put ' into the string.  We have to close the string, write \',
and re-open it.  Here's the algorithm in Python:

output = ''
for char in input:
    if char != "'": # Not a single quote
        output += char
    else: # Escape it.
        output += "'\\''"

I can send that patch, if you like.
