+Create extension that can disable symlink support:

+  adding a
+  adding b
+  $ cd ..
+
+Simulate a checkout shared on NFS/Samba:
+
+  $ hg clone -q unix-repo shared
+  $ cd shared
+  $ rm b
+  $ echo foo > b
+  $ hg --config extensions.n=$TESTTMP/nolink.py status --debug
+  ignoring suspect symlink placeholder "b"
+
+Make a clone using placeholders:
+
+  $ hg --config extensions.n=$TESTTMP/nolink.py clone . ../win-repo
+  updating to branch default
+  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
+  $ cd ../win-repo
+  $ cat b
+  a (no-eol)
+  $ hg --config extensions.n=$TESTTMP/nolink.py st --debug
+
+Write binary data to the placeholder:
+
+  >>> open('b', 'w').write('this is a binary\0')
+  $ hg --config extensions.n=$TESTTMP/nolink.py st --debug
+  ignoring suspect symlink placeholder "b"
+
+Write a long string to the placeholder:
+
+  >>> open('b', 'w').write('this' * 1000)
+  $ hg --config extensions.n=$TESTTMP/nolink.py st --debug
+  ignoring suspect symlink placeholder "b"
+
+Commit shouldn't succeed:
+
+  $ hg --config extensions.n=$TESTTMP/nolink.py ci -m1
+  nothing changed
+  [1]
+
+Write a valid string to the placeholder:
+
+  >>> open('b', 'w').write('this')
+  $ hg --config extensions.n=$TESTTMP/nolink.py st --debug
+  M b
+  $ hg --config extensions.n=$TESTTMP/nolink.py ci -m1
