Subject: [PATCH 3/3] Use active CPIO, FIND, and XARGS to set built-in defaults.
Message-ID: <1112.1139614602@lotus.CS.Berkeley.EDU>
URL: https://gitlist.dev/e/1112.1139614602%40lotus.CS.Berkeley.EDU

```
Move the sed program in the % : %.sh pattern into the shellsedprog
variable.  Add clauses to change the CPIO, FIND, and XARGS built-in
defaults if those variables are set.  With appropriate settings, all
the current tests pass on Solaris 8 with my personal bizarre setup.
I'll try on a modules-based AIX once the machine's back next week.

I don't really like how I build the sed program, but I can't think of
an easier / better way.
