Understood. I'm thinking about it this way - we have nonstandard shell
for historic reasons. Many tests from the test suite still works fine. I
want to test as much as possible of the shell Solaris people will be
using. If I just disable xpg_echo, I won't be testing that. The pain of
maintaining the tests is price for that.

However, if you see point in testing also xpg_echo enabled shell, we
might apply just the changes (echo -E) to where it matters and leave the
rest to be tested in the same way as official shell.

And if you can't trust 'echo' echo, what can you ? :)

Thank you
