Summary: searching for data with \0 in mmapf

Initial Comment:

searching for values with embeded nulls returns
incorrect results, eg:

import mmap,os
fp=open('foo','w+')
fp.write('foo')
fp.write('\1'*(mmap.PAGESIZE-3))
data='foo\0data'
fp.write(data)fp.write('\1'*(mmap.PAGESIZE-len(data)))
m=mmap.mmap(fp.fileno(),2*mmap.PAGESIZE)
fp.close()
print 'data found at:',m.find(data)
m.close()
os.unlink(foo)

returns 0 where mmap.PAGESIZE is required
