Fix code style

At least a general conformance to the same style if nothing else
Based on what appeared to be the most used or most sensible conventions which lead to the following
Braces around variables
Preserve quotes and quote paths
statements begin on the same line
No trailing white space
Respect 120 chars page width at least
Use brackets instead of back-ticks
Two space indent 4 space continuation
No logic was harmed in the making of this commit.
