[GRASS-dev] g.mlist: doesn't show a single raster?

[Ivan Shmakov]

	I've compiled a recent SVN (r30272) GRASS, and now getting a
	strange behaviour from `g.mlist' and `g.list'.  E. g.:

GRASS 6.3.svn (modis-sin-i):~ > g.mlist type=rast mapset=ivan 
GRASS 6.3.svn (modis-sin-i):~ > 

	This works well with GRASS 6.2.3 from Debian (though it takes
	noticeable time to complete):

GRASS 6.2.3 (modis-sin-i):~ > g.mlist type=rast mapset=ivan 
... 3106 lines skipped...

2006-08-brdf.a.albedo.altay.9.qa-mask
foo
GRASS 6.2.3 (modis-sin-i):~ > 

	Also (though it presumably is a different issue):

GRASS 6.3.svn (modis-sin-i):~ > gdb g.list 
...
(gdb) set args type=rast mapset=ivan 
Breakpoint 2, G_ls_format (list=0x807f4a8, num_items=3109, perline=0,
    stream=0x8056ec0) at ls.c:157
157             perline = screen_width / (max_len + 1);
(gdb) print screen_width
$7 = 80
(gdb) print max_len
$8 = 110
(gdb) 

	NB: the `max_len >= screen_width' case isn't handled properly!

(gdb) next
161         field_width = screen_width / perline;
(gdb) print perline
$9 = 0
(gdb) next
