revlog: don't try to partialmatch strings those length > 40 _partialmatch() does prefix matching against nodes. String passed to _partialmetch() actualy may be any string, not prefix only. For example, "e410be8603932e46a51298748a4b874739037fad or 300" is a good argument for _partialmatch(). When _partialmatch() searches using radix tree, index_partialmatch() C function shouldn't try to match too long strings.
