Commit Message

ls: incorrect column widths in -R mode

* The column widths for "ls -R" didn't always look right
* List() is called for each directory/subdirectory
* Global variable $Maxlen is increased by 1 unconditionally, despite the value being saved from the previous call
* When I tested "perl ls -R .." I observed $Maxlen values from 21-59, incrementing by 1 for each directory
* The entries for the subdirectories are printed with too much space
* When I compare the output of GNU ls, the column widths are calculated for each directory listed
* Fix this by making $Maxlen a non-global; it is only used in List() and the value between calls should not be saved
* Extra: remove unused variable $BlockSize
