If I understand correctly, this means that, given the following repos:

r1: import of file-1.h, file-2.h
r2: rename "file-1.h" into "file-1a.h" => file-1a.h, file-2.h
r3: rename "file-2.h" into "file-1.h" => file-1a.h, file-1.h

then

[1] svn cat .../file-1.h --revision 1

returns file-2.h of rev 1 because the filename identifies "file-1.h of
the HEAD revision, and subversion returns rev 1 of that file, which was
named "file-2.h" in rev 1;

and

[2] svn cat .../file-1.h@1

return "file-1.h" of rev 1;

and finally:

[2] svn cat .../file-1.h@1 --revision 3

returns "file-1a.h" of rev 3.

Correct ?
