 Or perhaps ls should have a flag that disables the automatic column
 sizing.
 
 Another approach is to forcibly set the column widths...  or just
 prune all column padding.
 
 The former isn't entirely trivial because there are a lot of cases.
 
 The latter would give something like
 
               -type b -o -type c \) -print0 | \
    -   xargs -0 ls -ldgTq | sort +9 > $LIST
    +   xargs -0 ls -ldgTq | sed 's/  */ /g' | sort +9 > $LIST
 
 although looking at this I am starting to have real doubts about that
 sort +9. It sorts the regular files and directories by name, but the
 devices by year...
