[PATCH] Tweak "make big" to catch if bigd/ already exists

[Trevor Murphy]

Hi, all. Please bear with me, as I'm still fairly green to vimpulse, git, git send-email, and what have you.

I prefer to use the 'make big' option. However, I can't do a 'git pull; make big' to get myself up to date.  Make complains that the bigd directory already exists.

Attached is a patch to fix that in the obvious way. But I feel like I must be missing something.

Surely other people would have encountered this by now if they also used the big file. Am I missing the compelling reason to avoid using it?

Anywho, thanks for your great work. I've committed to getting more comfortable with Emacs, and I just couldn't do it without vimpulse.
