Bug #49740 for autodie: autodie=system system(qw[ grep -P . 2]) broken "grep: invalid option -- ,"

"grep -P . 2" works from command line, and system, and IPC::System::Simple, but not with autodie=system echo >2 cat 2 grep -P . 2 perl -Mautodie=system -e " system qw[ grep -P . 2]" perl -MIPC::System::Simple=system -e " system qw[ grep -P . 2]" perl -Mautodie=system -MDevel::ModList -e 1 perl -Mautodie=:all -d:Trace -e " system qw[ grep -P . 2]" Show quoted text
