cmd_nvedit.c: clean up syntax highlighting

My text-editor (vim) has a bit of trouble syntax-highlighting the
cmd_nvedit.c file, because it apparently does not parse C
ifdef/else/endif. The following patch does not change the behavior of
the code at all, but does allow the editor to properly
syntax-highlight the file.
