Comment:

 We should fix the part of these that we can for cleanliness.  Most of the
 "if file_status()==FN_FILE then read_file_to_string" checks are silly:
 they could just be read_file_to_string with an appropriate response to
 errors.

 In fact, most file_status() checks should be considered suspect.
 Generally, instead of "may I do X with this file" then trying it, we
 should just try to do X and see if we get an error.
