Add another forbidden file name in submissions: prog.alt (prog.alt.c is allowed).
Modularise the checks for invalid filenames in entries. For instance in check_extra_file() there's no need to check each extra filename and then give the same error message changing the macro of the filename that's disallowed when we can just print the string being tested against. The only difference is that there's one if (with multiple checks) and instead of duplicating the same error message we just print it once with the string being tested against. Note that there are two sets of checks: one for extra files being required filenames and another for disallowed filenames.
Make sure to use the macros for the filenames, not the literal strings (e.g. use PROG_FILENAME not "prog").
Check filenames in alphabetical order (I think :-) .. very tired so maybe missed one or two).
Note that the function check_extra_file() CANNOT be used in every case so it's not used except in chkentry!
