So you just want the history for a single file?

 git log -p --reverse --pretty=email -- sql_iabbr.vim

That outputs a patch history for sql_iabbr.vim in mbox format, you can
import that into an empty repo with git-am.

(I had a look at the project, the history is simple with no merges
etc, so nothing like --first-parent is needed)

Cheers,
