First, IIRC gitweb requires Perl 5.8 _anyway_ because of unicode stuff.

No, you would need something like this code from gitweb.perl (used in
very rare cases where list form of open cannot be used, which means
when we need pipeline like for compressed snapshot, or redirecting
stdout and/or stderr to /dev/null like when getting type of possibly
not existing object in git_object)
# quote the given arguments for passing them to the shell
# quote_command("command", "arg 1", "arg with ' and ! characters")
# => "'command' 'arg 1' 'arg with '\'' and '\!' characters'"
# Try to avoid using this function wherever possible.
sub quote_command {
return join(' ',
map( { my $a = $_; $a =~ s/(['!])/'\\$1'/g; "'$a'" } @_ ));
}
Or you can use "open $fd, '-|'" to fork, an "manually" exec/system.
