I had not done any testing beyond p4 12.2 (linux). But running
the unit tests through 13.1 just now, they all pass.

There wasn't an explict test for symlinks, but I threw
one together quickly and it seems to work. Can you show
a bit more information about anything that potentially might
be odd with your install?
arf-git-test$ ls -l symlink
lrwxrwxrwx 1 pw pw 14 Apr 18 20:02 symlink -> symlink-target
$ p4 fstat symlink
... depotFile //depot/symlink

$ p4 print -q symlink | od -t x1a

No idea why I get an "nl" but you do not. If you run _without_
the "| od ...", then the shell prompt ends up on the same line
as the output? Any interesting shell or shell settings?

This code only happens on utf16 files. But running it by hand,
I cannot reproduce the different behavior:
$ p4 print -q //depot/f-ascii
three
line
text
$ p4 print -o - -q //depot/f-ascii
three
line
$ ls ./-
ls: cannot access ./-: No such file or directory
I'm again confused. Any hints you can give would be helpful.
