In this case, just reverse the string first. Then, the first set of '--' is
the real comment. Snip it, reverse it back, and carry on.

x = "code --fake comment -- real comment"

becomes

x = "tnemmoc laer -- tnemmoc ekaf-- edoc"

then becomes

x = " tnemmoc ekaf-- edoc"

which finalizes to

x = "code --fake comment "
