volFieldValue produces empty lines
Functionality to add/problem to solve
volFieldValue::read prints a newline when it does a read (even though it prints nothing else). This produces unnecessary empty lines at startup.
Run e.g.
incompressible/pisoFoam/RAS/cavity
and there will be about 20 empty lines from the FOvolFieldValue use of volFieldValue in various permutations.
Proposal
volFieldValue::read, surfaceFieldValue::read : do not output a line if nothing else has been printed. Or always output at least something?
