Sanity checks

[pontacko]

Hello,

SDConfig.h:

uint8_t _valueIndex;     // position in _line[] where the value starts
			//  (or -1 if none)

unsigend integer 8-bit (0-255)

SDConfig.cpp:
_valueIndex = -1;
overflow to 255

if (_valueIndex < 0) {
will never happen?!

regards & thanks for this project

Ouch. Good catch. Because _valueIndex is an unsigned integer, it can never be less than zero. uint8_t range is 0..255.

I should change the code so that:
0 is the initial value of _valueIndex.
A _valueIndex value of 0 after the line has ended indicates no = was in the line.
