Example code writefile() and appendfile()

[jfseaman]

In PSRamFS_Test.ino lines:
191: if( file.write( (const uint8_t*)message, strlen(message)+1 ) ) {
214: if( file.write( (const uint8_t*)message, strlen(message)+1 ) ){

The "+1" causes writing of buffer contents to include the buffer terminating NULL (\0).
This may be intentional by the CO (code originator).

It caused me some thinking on why there were extra characters returned from readfile.

It was a common "error" for my "C" students in the 80's writing in K&R C on MS-DOS and CP/M systems. ;)
