Greetings,

Attached patch fixes BZ #18660 -- overflow in getusershell.

Note: the file does not follow GNU coding convention, should I make a
whitespace-only pass over it?
Note: Tobias proposed a different patch:
https://sourceware.org/bugzilla/attachment.cgi?id=8502, but I like my
patch better.

P.S. AFAICT, this is nearly impossible to test :-(

Thanks,

        [BZ #18660]
