#9 failure in reverse cache lookup

[Real Name]

names with character '-' like
"xxxxxxxxx.dip.t-dialin.net"
will be responded incorrect
-->"xxxxxxxxx.dip.t"

reason:
file cache.c
function cache_lookup_ip
line 110
added line[i]=='-'

works well jet, but i dont think that's the way
it should do.

better you change the term in
"is not a space character"
because ..i dont know? perhabs its saver?

that's all :-)
