Yep - that's what I thought was reasonable behaviour as well and what my 
submission does.

Sure, I rebased the series to have the fix-ups at the right places, but 
didn't think it was an interesting enough change to rate a full 
re-submission. The series at git://github.com/samv/git branch 
perl-Config has the minor change put into the place it was introduced. I 
put a little note to this effect after the --- line.

I'm not quite sure what you want squashed where, maybe just edit the 
below list to be how you'd like it,

pick d43238e perl: add new module Git::Config for cached 'git config' access
pick 5ea135d perl: make Git.pm use new Git::Config module
pick b2865bc perl: make Git::Config use --null
pick 28eecdc perl: fix no value items in Git::Config
