#245 "find" doesn't deal with $'s correctly

[sistisette]

I know this is pretty known, but for some reason it was not in the tracker, so here it is.

The find panel won't search for an object with a dollar parameter.

For example, in a patch containing a [r $1],
neither "r $1" nor "r \$1" work as a search string.

The former returns
r 0
... couldn't find

while the latter returns
r \\$1
... couldn't find
