two bugs fixed in ramfs 1.4

[bousch@suntopo.matups.fr (Thierry Bousch)]

Hello all,

some people in Mausnet have noticed a bug in RAMFS 1.4 that prevented it
from working with GEMINI (because of a bad return code in
ram_readlabel).

Another bug, more annoying for those using decent shells :-) like tcsh,
is that RAMFS did not update the date/time fields of a directory when
you removed an item from it.

You should apply the following patch to ramfs.c to upgrade it from
version 1.4 to version 1.5.  It fixes these two bugs. 

Thierry.
