The attached match makes dmenu print out the input text as it is
entered, rather than just the final selection.
This is useful if you make surf run the following shell
script snippet...
dmenu -r -p find: |\
while read -r find; do
xprop -id $xid -f _SURF_FIND 8s -set _SURF_FIND "$find"
done
... which gets you [the basics of] usable incremental search.
