BUG: Github: Display empty page in search mode

@captainko I've forked vb4c (archived) and fixed this issue in https://github.com/b-coimbra/vimch/commit/824a2b862638cc4f528c746e26138aff88b07e2c.

You can either use my release vimch 0.0.3 or simply add the line that fixes the issue in your local extension files.

I'll try to provide other fixes and improvements in the future in my fork as I've gotten too used to cVim to use any other Vim extension.
