Works fine for me. Please give a complete recipe starting from emacs -Q.
Here's mine, using svn 1.7.8. I assume you are talking about
subdirectories, otherwise it makes no sense.
cd /tmp
svnadmin create repo
mkdir -p proj/sub/dir
cd proj
touch 1 sub/2 sub/dir/3
svn import . file:///tmp/repo/proj/trunk -m 'import'
cd ../
rm -rf proj
svn checkout file:///tmp/repo/proj/trunk proj
svn checkout file:///tmp/repo/proj/trunk proj2
cd proj2
echo foo >> sub/dir/3
svn commit -m "change" sub/dir/3
cd ../
ln -s proj/sub/dir
emacs-24.2 -Q dir/3 & # visit file via linked directory
"Followed link to /tmp/proj/sub/dir/3" appears in echo-area.
SVN-1 appears in mode-line.
M-x vc-update
-> file is updated with "foo"

I'm sorry for the false alarm. I still think there is a bug, but not the one I
reported.
This works
emacs -Q /path/to/symlink-directory/file
where /path/to/symlink-directory points to an SVN controlled directory.
However, if the variable vc-cvs-stay-local is set to nil in .emacs, then the
emacs fails to notice that symlink-directory is SVN controlled.
Now, this may or may not be intended, but I believe it is a bug nevertheless.
If it is not intended, there's the bug. If it is intended, then the
documentation for vc-cvs-stay-local (not to mention the name of the variable
implying that it affects CVS repositories only, but the documentation makes it
clear this is not the case) is wrong:
Non-nil means use local operations when possible for remote repositories.
This avoids slow queries over the network and instead uses heuristics
and past information to determine the current status of a file.
If value is the symbol `only-file' `vc-dir' will connect to the
server, but heuristics will be used to determine the status for
all other VC operations.
The value can also be a regular expression or list of regular
expressions to match against the host name of a repository; then VC
only stays local for hosts that match it. Alternatively, the value
can be a list of regular expressions where the first element is the
symbol `except'; then VC always stays local except for hosts matched
by these regular expressions.
Cheers,
Juha

It makes no difference for me whether I set vc-cvs-stay-local,
vc-svn-stay-local, or vc-stay-local to nil or t. The recipe I posted
still works fine. Do you have a recipe starting from emacs -Q that shows
the problem?

More information was requested almost a year ago, but no further
progress seems to have been made. I'm closing this bug report now, but
if this problem still persists, please reopen it.
