Hi,
I've spent many frustrating hours cornering this bug. Here's a short
testcase to reproduce it:
#!/bin/sh
cd /tmp
rm -rf z b
mkdir z z/a z/b
echo ha >z/a/file
ln -s z/b
cd b
cat ../a/file
emacs -Q ../a/file # buffer-file-name = /tmp/a/file
Why doesn't emacs behave like cat or vim? Isn't this behavior a bad default?
Thanks.

Okay, so expand-file-name defined in src/fileio.c is buggy:
#!/bin/sh
cd /tmp
rm -rf z b
mkdir z z/a z/b
ln -s z/b
cd b
emacs -Q --batch --eval='(error (expand-file-name "../a"))'
realpath "../a"
Why such horribly convoluted logic? What could be more straightforward?

Please note that we have a dedicated bug list. Bugs reported to
emacs-devel have a higher chance of being ignored.
In this case, it sounds like you rediscovered
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8035
I agree it is sub-optimal.

Right; last activity in Feb 2011. I'm not interested in reporting
anything: please tell me more about how to fix this bug, and I'll
write the patch now.

I don't know how. If I did, I'd comment in the bug report.
I encourage anyone who does to do so.
