The option only affect parallel runs, it instructs the code to recollect 
the wavefunction files from all the processor pools in a single 
directory, as if the calculation was run with only one pool. It has no 
specific relationship with el-ph calculations. I don't know if el-ph has 
been implemented with pools parallelizations, but if it hasn't you can 
still use pools in the scf calculation using the wf_collect option.
