EPSF-1.2 preview bitmaps

I have a question about some EPS files I received.  They were created
by Adobe Illustrator 1.1, and have a non-standard preview bitmap.

Instead of:
	%%BeginPreview: 340 107 1 107

They have:
	%%BeginPreview
	%%ImageWidth:340
	%%ImageHeight:107
	%%ImageDepth:1
	%%BeginImage:107

I requested the EPSF-1.2 specification from the ps-file-server, and it
doesn't say anything about device-independant preview bitmaps.

I'm assuming that this is a private format used before the form of the
device-independant previews were finalized in EPSF-2.0.  But, as some-
one who claims to be able to import EPS files, should I have to worry
about these anachronisms, or should I go ahead and support them anyway?

Thanks,
