False negative from assert_have_been_called_with when args include a literal pipe

[mattness]

Q	A
OS	macOS and Linux
Shell & version	bash 5.3.3 (macOS) and bash 5.2.32 (Linux)
bashunit version	0.24.0 (both)

Summary

assert_have_been_called_with will produce a false negative when the spied command's args include a literal pipe

Current behavior

After creating a spy for a command and then calling that command with arguments that contain a literal pipe (|) character, assert_have_been_called_with will not compare the expected value against the correct actual value, and the assertion will fail erroneously.

How to reproduce

This test currently fails:

function test_grep_with_or_pattern_arg() {
  spy grep
  grep -E 'foo|bar'
  assert_have_been_called_with grep '-E foo|bar'
}

Output:

✗ Failed: Grep with or pattern arg
    Expected '-E foo|bar'
    but got  '-E foo'

Expected behavior

assert_have_been_called_with grep '-E foo|bar' should pass
