/* Define the 8 different sort function variants required for each sortkey.
- KEY_NAME is a string describing the sort key, e.g., ctime, atime, size.
+ KEY_NAME is a token describing the sort key, e.g., ctime, atime, size.
KEY_CMP_FUNC is a function to compare records based on that key, e.g.,
ctime_cmp, atime_cmp, size_cmp. Append KEY_NAME to the string,
'[rev_][x]str{cmp|coll}[_df]_', to create each function name. */
