No need for trailing `.' in commit message titles

Personally, I'd hoist the #ifdef part into a standalone function
since I find mixing CPP and C conditionals confusing.

disclaimer: I'm an easily confused person and don't usually
program in C, though.

`nc' isn't widely installed, its supported flags vary between
implementations, and our test suite doesn't currently use it.
I suggest either using a small bit of Perl or writing a t/helper
program to do its job.

Finally, hard tabs should be used for indentation throughout.

I'll wait on others to comment since I haven't looked at git
hacking in a while.

Anyways, I think this feature could be useful for me, too :>
Thanks.
