The problem is in exit(), not sed.  Put a flush() before each exit() in the
sed sources and you should be fine.

I have not yet had this problem, but it does seem that a version of fix that
ignores differences in whitespace IS a good solution to the problem, barring
fixing every mailer in use.  Patch does this, doesn't it?

Using the Minix 1.2 shell with the data area set to 32000 bytes, sed with the
described fix, and the version of chmod that I posted to the net, I have been
able to successfully unshar every shar that I have attempted, including all of
ast's 1.2 "Definitive Update".   I have not attempted the Turbo-C patches, 
however.
