Renaming inc/tweaks.php to inc/extras.php and including by default in functions.php
Use a filter for wp_title instead of hard-coding things in header.php
Corrected two typos

"don't" with &apos; should be more correct than &rsquot; (or is it better to escape it \' ?)

show space using &nbsp; instead of actual space, as Github trims it in markdown rendering

Deals with Issue #123
add &nbsp; in replacement text too
use code tags in markdown instead of backticks to be able to use &nbsp;
