[RFA] memattr.c: improve output

[Elena Zannoni <ezannoni@cygnus.com>]

JT, this patch reformats the output of 'info mem' to look a little more
like breakpoint output. 

Also, it improves a bit the help messages.


(gdb) i m
Num Enb Low Addr           High Addr          Attrs 
1   y  	0x0000000012345678 0x0000000012345679 rw nocache 



(gdb) mem 0x12345678 0x12345680 rw 8 nocache
(gdb) i m
Num Enb Low Addr   High Addr  Attrs 
1   y  	0x12345678 0x12345680 rw 8 nocache 



OK?
