Re: [PATCH] Add expandargv test to libiberty testsuite.

[DJ Delorie <dj at redhat dot com>]

I was thinking something like this:

const char *test_data[] = {
  "data to write\nto some file N"
  "data to write to\r\nsome file N+1",
  0, /* ends list of files */
  "argv[1]",
  "@argv[2]",
  0, /* ends list of "before" command line */
  "argv[1]",
  "argv[2]",
  "argv[3]",
  0, /* ends list of "after" command line */
  "start\bof\bsecond\btest\b",
...
  0,
  0
};

The test would just cycle through the whole array, building and
running tests as it found them.  Testing for \0 might be tricky; we'd
have to have some hook that says "When you see \b, write \0".  Output
files would have predetermined names, like "file1.txt" through
"fileN.txt" so the tests can put the right @file in.

This way, we avoid the problem of checking binary files into cvs/svn
(cr/lf conversions happen by accident a lot) and keep everything in
one source file.  It also lets us comment the test cases.
