I see. The difference comes from virtualedit: I have it set to
all, you seem to have it left to the default (which is unset). As a
workaround, you can triple the last %, so that `` jumps to the right
place. :) It's also probably a good idea to search for \\xxx{ rather
than \\xxx\>, to avoid matching the definition of \xxx. To summarize
it:

/\\xxx{^Mdt{d%%%%x``x@qq
^ ^^

/lcd
