FIND string! tag! misses < and >

Submitted by: BrianH

FIND string! does an implicit FORM of its second argument when not a string type, but apparently just searches for the raw string data of other string types. This is wrong for FIND string! tag!, where it should be searching for the angle brackets as well.

(This is split off of #1159)

>> find "<a>" <a>
== "a>"  ; should be "<a>"
>> find/tail "<a>b" <a>
== ">b"  ; should be "b"
>> find/match "<a>b" <a>
== none  ; should be "b"
