Ensure that loaded functions increment the command count

Browse source 
Since we don't know what a loaded function (via Guile or load) may
do, increment the command count just in case.

* src/function.c (struct file_table_entry): New adds_command bool.
(FT_ENTRY): Initialize it to 0 for built-in functions.
(expand_builtin_function): If adds_command, increment the count.
(define_new_function): Set adds_command for loaded functions.
