[PATCH 1/2] Rename fields of cli_interp_base::saved_output_files

[Tom Tromey <tromey@adacore.com>]

This renames the fields of cli_interp_base::saved_output_files, as
requested by Simon.  I tried to choose names that more obviously
reflect what the field is used for.  I also added a couple of
comments.
