The problem is that there is no fixed 1:1 relationship between long
and short names. On my system, I have

progra~1
progra~2
Program Files
Programme

(This comes from installing a German version of Win95 and English
software :-)

It is impossible to tell which alias belongs to which long name,
unless you read the directory. The point of the dcache is to
not read the directory, of course.
