>Description:
	with the current usr.bin/ftp, the behavior of "macdef" command is
	rather non-intuitive.
	- if you "macdef" the same macro name twice, they will be entered to
	  the macro database as a different macro.  the first one defined is
	  actually invoked on $foo (2nd and other definitions are in memory,
	  but will not be used).
	- if you define macro that expands to longer string, $n reference
	  will not work correctly.
>How-To-Repeat:
	- repeat "macdef foo" for 16 times.  see "Limit of 16 macros have
	  already been defined." error.
	- do the following.

ftp> macdef hoge
Enter macro line by line, terminating it with a null line.
$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0
$1$1$1$1$1
$2$2$2$2$2

ftp> $hoge get
it will be expanded to the following three commands:
hogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehoge
ogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogeogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogeogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogeogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogeogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehogehoge
(empty string)

ftp> macdef hoge
Enter macro line by line, terminating it with a null line.
$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0
$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0
$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0$0

ftp> $hoge get
segmentation fault

>Fix:
	revisit usr.bin/ftp/domacro.c
