Most of the new code is in the new file fnameconv.c. The patch lightly
touches some other files, mostly flist.c and the addition/extension of
-some utility functions. I took the opportunity to fix an argument
-parsing buffer overflow bug in main.c. Note that you'll need to run
-autoconf and 'make proto'.
+some utility functions.
+Note that you'll need to run 'make proto' after applying this patch.
