[RFA/Testsuite] help.exp

[Elena Zannoni]

The recent changes to help.exp eliminating the wildcards introduced a few
failures on the powerpc.

How about this to deal with the difference in output for the powerpc
vs. other targets?

Ooops, didn't mean to do  that.  ;-)

OK with me (the author of the breakage).
Or you could just use a parenthesis to make the
powerpc command output optional...

Hi Elena,

I would rather have a '.*' in there instead of the test for a specific
target.

You don't need to resubmit: just add the '.*' and post the final
version.

Fernando

Good idea, more specific than my suggested '.*'.  But we don't
need to be so stringent in this case.  As long as we see the 
generic ones the help is working.  

Unless Elena wants to test if these commands show up for the powerpc
targets help.  In this case, neither my suggestion or yours are 
checking for it. :-(

If that is the case, we will have to go with Elena's original patch.

That is the way it was originally. That works fine with the powerpc.

Nah, I don't really want to be that specific.

But you guys decide, if we got rid of the wildcards do we want them back?

I was only deleting them where I thought they were unnecessary.
In this case, I was wrong, 'cause I didn't know PPC had its own
variants.  So yes, it would be appropriate to put that one back.

It looks good to me.  I prefer the target-sensitive test to a wildcard
expression, because the target-sensitive test expresses the success
conditions more precisely.

I proofread it, but I did not test it.

I recommend this patch for approval.
