Here's the list of squashed commits (for more info, see PR #378). - Define guicolor_T as a typedef in syntax.h - Move a big chunk of code from structs.h to buffer_defs.h - Move aco_save_T from structs.h to fileio.h - Move option_table_T from structs.h to hardcopy.h Aditionally: - Move the printer_opts global to hardcopy.c - Delete structs.h. Include buffer_defs.h where structs.h was included before. - Add header guards to option_defs.h - Put mark types and constants in new mark_defs.h - Move undo structs to undo_defs.h - Move memfile structs to new memfile_defs.h - Move expand_T and cmdmod_T to ex_cmds_defs.h - Move memline_T to memline_defs.h - Move many defs and types to ex_eval.h - Move syntax related types to syntax_defs.h - Move struct memfile to memfile_defs.h - struct buffblock and struct buffheader moved back to buffer_defs.h - Move some datatypes to hashtab.h and eval_defs.h - Move the buffer_defs.h include and TODOs for remaining unrelated types in buffer_defs.h
