Use list form of open for running git commands and reading their
output through pipe, for example
open my $fd, "-|", $GIT, "rev-list", "--header", "--parents", $hash
instead of
open my $fd, "-|", "$GIT rev-list --header --parents $hash"
Single letter options use ' instead of " as quotes, according to style
used in list form of magic "-|" open.

The correct solution would be to use safe_pipe_capture or,
what's better, use Git.pm, when it will be in released version.
Should have no impact on speed. Using ' instead of " could bring
insignificant speedup.
