[Ml-yokadi] Fix backtick bug in manpage

[Sébastien Renard]

Hello,

Thanks for using Yokadi. I've reviewed you patch and I do not understand the 
fix.
http://github.com/ryanakca/yokadi/commit/9cef988004038651d71ad4bb3b8bd1f92a2f53b4

Backquotes seems correct when viewing page with man ./yokadid.1. I can 
copy/paste line in a terminal and it works. 
Which version of man do you use ? I use man 1.6f.

Regards
