Reverse DNS Lookup Zone File and Whitespace

I have been struggling to get my reverse look up working on my DNS (bind) server for a LONG time... The problem I finally figured out:

$TTL 3D
@       IN      SOA     ns.linux.bogus. hostmaster.linux.bogus. (
                        199802151 ; Serial, todays date + todays serial
                        8H      ; Refresh
                        2H      ; Retry
                        4W      ; Expire
                        1D)     ; Minimum TTL
                NS      ns.linux.bogus.

; NO WHITESPACE!!!!
    1               PTR     gw.linux.bogus.
    2               PTR     ns.linux.bogus.
    3               PTR     donald.linux.bogus.
    4               PTR     mail.linux.bogus.
    5               PTR     ftp.linux.bogus.

See the spaces in front of the 1, 2, etc...? Those cannot be there for whatever reason.
