Merge branch 'avoid-pipes-in-svn-tests'

It is a good idea in general to avoid pipes in test cases, as it makes
things more debuggable to have files to inspect (instead of ephemereal
piped data that is long gone).

This also seemed to work around a problem where MSYS2' Perl would
segfault which may, or may not, still be present today.
