  Take for instance a look at hppa-tdep.h:
my patch changes
<<<hppa-tdep.h>>>>
extern struct hppa_objfile_private *
hppa_init_objfile_priv_data (struct objfile *objfile);
<<<hppa-tdep.h>>>>
into:

<<<hppa-tdep.h>>>>
extern struct hppa_objfile_private *
  hppa_init_objfile_priv_data (struct objfile *objfile);
<<<hppa-tdep.h>>>>

Your suggestion would lead to:
<<<hppa-tdep.h>>>>
extern struct hppa_objfile_private * hppa_init_objfile_priv_data (struct
objfile *objfile);
<<<hppa-tdep.h>>>>

on a single line (might have been corrupted by my mailer...)
91 column wide...

but if you look at the rest of the hppa-tdep.h file, you will find:

<<<hppa-tdep.h>>>>
extern struct value *
  hppa_frame_prev_register_helper (struct frame_info *this_frame,
                                   struct trad_frame_saved_reg *saved_regs,
                                   int regnum);

extern CORE_ADDR hppa_read_pc (struct regcache *regcache);
extern void hppa_write_pc (struct regcache *regcache, CORE_ADDR pc);
extern CORE_ADDR hppa_unwind_pc (struct gdbarch *gdbarch,
                                 struct frame_info *next_frame);

extern struct minimal_symbol *
  hppa_lookup_stub_minimal_symbol (const char *name,
                                   enum unwind_stub_types stub_type);

extern struct hppa_objfile_private * hppa_init_objfile_priv_data (struct
objfile
 *objfile);

extern int hppa_in_solib_call_trampoline (struct gdbarch *gdbarch,
                                          CORE_ADDR pc, char *name);
extern CORE_ADDR hppa_skip_trampoline_code (struct frame_info *, CORE_ADDR
pc);
<<<hppa-tdep.h>>>>

  So you can see that the ugly formatting, I proposed is already
used twice.
  I found 37 occurrences listed below,
should we considered those as badly formatted?
