t9700-perl-git.sh is broken on some configurations

Hi,

It looks like t9700-perl-git.sh is broken on one machine I use but not on my laptop since commit d53c2c67380f769f91fd45cc8c63a5883245ccca (mingw: fix t9700's assumption about directory separators, Jan 27 17:19:56 2016).

I get:

------------------------

Indeed on the command line I get:

------------------------ $ t/t9700/test.pl ok 2 - use Git; Bareword found where operator expected at t/t9700/test.pl line 36, near "s/\\/\//gr" syntax error at t/t9700/test.pl line 36, near "s/\\/\//gr" Execution of t/t9700/test.pl aborted due to compilation errors. ------------------------

A quick look at t/t9700/test.pl line 36 was not enough for me to spot the problem.

Perl version is: perl 5, version 18, subversion 2 (v5.18.2) built for x86_64-linux

The machine is running CentOS 6.5.

Thanks, Christian.
