fixed a bug of StringScanner#pre_match after calling the StringScanner#match?.

Test Script:

require 'test/unit/assertions.rb'
include Test::Unit::Assertions
require 'strscan'

s = StringScanner.new("This is a test")

s.match?(/\w+/)
assert_equal("This", s.matched)
assert_equal("",     s.pre_match)

s.scan(/\w+/)
s.match?(/\s/)
assert_equal(" ",    s.matched)
assert_equal("This", s.pre_match)

puts :ok
}}}
