On my latop, if use 'echo non-existing*' in the if command, the
script will exit immediately, looks like the glob failure is
considered an error of ERR_EXIT. And changing to
{ echo non-existing* } always { TRY_BLOCK_ERROR=0 }
doesn't help, it still exits immediately. In the contrast, using 'fn'
won't trigger ERR_EXIT.
