Subject: Move the "taint_mode" option from Test::Valgrind::Command::PerlScript to Perl
X-Git-Tag: v1.02~18
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FTest-Valgrind.git;a=commitdiff_plain;h=11eeabaad0bbb6db15b9c967fae94cd7388f0012

Move the "taint_mode" option from Test::Valgrind::Command::PerlScript to Perl

But keep in Test::Valgrind::Command::PerlScript the automatic discovery for when we know the file.
