[PATCH 2/2] t3404: be resilient against running with the -x flag

[Johannes Schindelin <johannes.schindelin@gmx.de>]

The -x flag (trace commands) is a priceless tool when hunting down bugs
that trigger test failures. It is a worthless tool if the -x flag
*itself* triggers test failures.

So let's change the offending tests so that they are a bit less
stringent and do not stumble over the "+..." lines generated by the -x
flag.
