* Put a history comment into the header struct.
* Inputs:
* argv: Command line history to add to comments.
* in_hdr: Incoming header struct to use.
* Outputs:
* out_hdr: Outgoing header struct to add to.
* Assumptions:
* If no incoming struct then value is NULL.
* Algorithm:
* Calculate length of all comment strings, malloc and then set via
* rle_putcom.
