Harmonize the newly ported test unit-tests/t-reftable-merged.c
with the following guidelines:
- Single line control flow statements like 'for' and 'if'
  must omit curly braces.
- Structs must be 0-initialized with '= { 0 }' instead of '= { NULL }'.
- Array indices must be of type 'size_t', not 'int'.
- It is fine to use C99 initial declaration in 'for' loop.

Seems like I spoke too soon, some of my comments from the previous
commit have been addressed here. Nice.
