split -- V1.1

Mon Feb 29 19:08:54 AEST 1988
After a humbling lesson in argument passing, here is a fixed
up version of split.
This one should work on Apollos and Suns.
Usage:
split file -- makes file.ps from fil
split -ifile -oblat.ps -- makes blat.ps from file
split file1 file2 file3 -fCourier -- makes file1.ps, file3.ps, file3.ps in
the courier font.
Note that you can go "split files switches" or "split switches files"
The -i and -o switches are mostly for you PC guys who cant handle filenames
like this.that.and.the.other, as the program wants to just stuff a .ps
on the end.
Let me know if there are any problems.
