Changes for COMMON.H by Andreas Scherer, January 2021.

This set of changes modifies the output behaviour of the CWEB system.
Instead of writing directly to the C or TeX file as described in the
manual, the current run is documented in a temporary output file which is
copied to the expected file in the last moment.  In case of an user abort,
previous results are not destroyed.

For a complete history of the changes made to COMMON.H see COMM-PATCH.CH.
