Hi.
I will check this patch in in a few days if there are no objections.
It just adds const to source_file_name.
[fyi, I have some other pending patches that use const char *'s for
file names that depend on this one. This one is standalone
so I've separated it out.]

* top.c (source_file_name): Make const char *.
* top.h (source_file_name): Update.
* cli/cli-script.c (source_cleanup_lines_args): Make old_file
const char *.
(script_from_file): Change FILE arg to const char *.
* cli/cli-script.h (script_from_file): Update.
