(cp_option_init): New function.
(copy_reg): Remove now-unused function.
(do_move): Set up for and use `copy.c (copy)' in place of copy_reg.
Set up for and use `remove.c (rm)' in place of unlink.
Remove global declaration of backup_type.
(simple_backup_suffix): Default to `~', not `.orig'.
Use PARAMS, not __BACKUPFILE_P.
(find_backup_file_name): Add parameter, backup_type.
Remove the `unsigned' from some `unsigned char*' parameter types.
Add casts via UCHAR where necessary to avoid problems with unwanted
sign extension. Based on a patch from Kaveh Ghazi to appease Irix4's
cc compiler.

Move function-spanning `#if ...BSIZE' stmt to follow inclusion of
sys/param.h since BSIZE is sometimes defined in sys/param.h.
Based on a patch from Philippe De Muyter.
Remove definitions of those symbols.
* src/csplit.c: Move inclusion of regex.h/rx.h to follow system.h
since it now includes limit.h which defines RE_DUP_MAX.
* src/nl.c: Likewise.
* src/tac.c: Likewise.
