For this snippet of code perl mode gets the colors wrong:

return 'W' if               #/^Not Available on Mobile/m;    #W=Web only
    /This video is not available on mobile devices./m;
#After the m all is the wrong color.

Indeed, the code did not handle the case of a comment between the "if"
and the "/": it treated this slash as a division operator.
I installed a patch into the "master" branch which should fix it,
