commit ee5ec756218c852385c5ba5ef0f75b47ba59ec39
Author: Aaron Marcher <me_AT_drkhsh.at>

Commit: Aaron Marcher <me_AT_drkhsh.at>
CommitDate: Sun May 6 22:28:56 2018 +0200

    Fix coding style
    
    - Use block for single statement ifs
    - Keep lines to reasonable length (current debate as to reasonable)
    - When functions return -1 for error test against 0 not -1
    - Do not indent cases another level
    - Do not test against NULL and 0 explicitly
    - Use tabs for indentation, use spaces for alignment
