2.6.0-test3-mm1 /proc/ikconfig/config adds space after numbers

2.6.0-test3-mm1 /proc/ikconfig/config adds space after numbers

[Jurriaan]

2.6.0-test3-mm1:
After every number in /proc/ikconfig/config there's an extra space.

This leads to messages like

.config:244: symbol value '1 ' invalid for
SCSI_SYM53C8XX_DMA_ADDRESSING_MODE

and lots more.

Kind regards,
Jurriaan

Yes, I've seen that and I have a patch for it somewhere.
I'll dig it up and post it.

Thanks,
