import with add and addremove -- symlink walking should _not_ screwup.

  $ hg add

  adding bar

  adding baz

  adding foo

  $ hg forget bar baz foo

  $ hg addremove

  adding bar

  adding baz

commit -- the symlink should _not_ appear added to dir state

  $ hg commit -m 'initial'

  $ touch bomb

again, symlink should _not_ show up on dir state

  $ hg addremove

  adding bomb

Assert screamed here before, should go by without consequence

== fifo & ignore ==

  $ hg init test; cd test;

  $ rm a.c

  $ rm dir/a.o

try symlink outside repo to file inside

== cloning symlinks ==

try cloning symlink in a subdir

1. commit a symlink

  $ cd ../../..

  $ hg stat

  ? a/b/c/demo

  $ hg commit -A -m 'add symlink in a/b/c subdir'

  adding a/b/c/demo

2. clone it

  $ cd ..

  $ hg clone clone clonedest
