Finalize refactoring of string comparisons

Browse Source 
Unify the comparison idioms use.
Always use `if(!strcmp())` for "if string equals"
and `if(strcmp())` for "if string is not equal".
Never use `== 0` and `!= 0` with `strcmp()`.

Minor reformatting of the code immediately surrounding the
refactored lines.
