[imp] Quota driver Command

[mtecles at biof.ufrj.br]

Two problems with the quota driver "Command.php" (IMP 4 and 5).

Problem 1. 
The use of volumes generates long names for the partitions, wich 
wraps the response line of the quota command (Debian 6). As the  
result, IMP displays "No limit". Horde logs:

NOTICE: HORDE [imp] PHP ERROR: Undefined offset: 2 [pid 4207 on line 
87 of "/var/www/horde/imp/lib/Quota/Command.php"]
NOTICE: HORDE [imp] PHP ERROR: Undefined offset: 1 [pid 4207 on line 
88 of "/var/www/horde/imp/lib/Quota/Command.php"]

Sugestion for the quota driver Command.php:

Use "quota -uw" in the function getQuota. That is:

$cmdline = $this->_params['quota_path'] . ' -uw ' ...

instead of 

$cmdline = $this->_params['quota_path'] . ' -u ' ...

The w option avoids wrapping.

Problem 2.
Command drive fails to determine the disk block size and IMP displays 
wrong numbers. Using 
$blocksize = 1024;
solved the problem for me.
