[Info-vax] Why does this DIFF command fail, then run fine the 2nd time around?

Not a new problem with V8.4-2L2, easily reproducible on OpenVMS Alpha V8.2 as well.

If you issue a $ SET WATCH FILE/CLASS=ALL before the DIFF command, it shows

...
%XQP, Thread #0, Read only directory access (39801,21,0)
%XQP, Thread #0, Directory scan for: TEST.TXT;4294934528, Status: 00000001   <<< ???

%DIFF-F-OPENIN, error opening USERDISK1:[HALLE.ITRC.B.*]TEST.TXT; as input

...

for the first DIFF command and

...
%XQP, Thread #0, Read only directory access (39801,21,0)
%XQP, Thread #0, Directory scan for: TEST.TXT;0, Status: 00000001

when repeating the DIFF command.

Maybe some data initialization problem in P1 space ?
