[petsc-users] Read from file failes

[Jose E. Roman]

If bfw62a.petsc and bfw62a.petsc are from the SLEPc distribution, then they contain real scalars, so you cannot read them from a program that goes --with-scalar-type=complex
You should read a file generated by you, or test examples that do not read files.
