 Log Message:

 Make a SMALL dmesg even smaller.
 
 When compiled -DSMALL, dmesg does nothing at all with the kernel
 timestamps (it processes no options to be told what would be the
 user's desire) so make it truly do (almost) nothing, rather than
 some botched partial processing of them.
 
 The "almost" is that a SMALL dmesg will now ignore spaces at the
 beginning of each new message line ... those are (vanishingly)
 unlikely to occur, as the kernel puts the timestamp (which starts
 with '[' there) - fixing this would have meant even more #ifdef's
 as the code that ignores that leading space is the only remaining
 thing that (in a SMALL) dmesg looks at the value of the "tstamp"
 variable, and if we don't keep some use of it, gcc complains...
 
 These changes affect only SMALL dmesg (as installed on boot
 floppies, etc) and have no intended effect on the version that's
 installed on a normal (full size) running system.
