Even when I run individual test scripts by hand, I prefer to have a
file catching all output of the test, because I don't like it when the
test output floods my terminal (especially with '-x'), and because the
file is searchable but the terminal isn't.  And that's exactly what
'--verbose-log' does.

Redirecting the '-v' output (i.e. stdout) alone is insufficient,
because any error messages within the tests and the '-x' trace go to
stderr, so they still end up on the terminal.  Therefore I would have
to remember to redirect stderr every time as well.

I find it's much easier to just always use '--verbose-log'... except
for the length of the option, that is, hence this patch.
