With the merge of this topic reverted out of 'seen', here is how it
used to end:

    $ cd t && sh t9152-svn-empty-dirs-after-gc.sh -i -v; echo $?
    Initialized empty Git repository in /home/gitster/git/t/trash directory.t9152-svn-empty-dirs-after-gc/.git/
    Can't locate SVN/Core.pm in @INC (you may need to install the SVN::Core module) (@INC entries checked: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.40.1 /usr/local/share/perl/5.40.1 /usr/lib/x86_64-linux-gnu/perl5/5.40 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-linux-gnu/perl/5.40 /usr/share/perl/5.40 /usr/local/lib/site_perl) at -e line 2.
    BEGIN failed--compilation aborted at -e line 2.
    1..0 # SKIP Perl SVN libraries not found or unusable
    0

The largest difference being that we used to exit with 0 so the
overall "make test" passed, but it no longer is the case.
