When dumping a hash, YAML::Syck outputs a trailing whitespace at the end
of the first line, so that the first line is "--- \n".

This causes various problems: trailing whitespace is invisible in most
text editors; other text editors trim trailing whitespace; which ends up
in tests that fail even though the output appears identical.

Test file attached.

(This is a form-reply that isn't specific to your particular report)

YAML::Syck has just acquired one new maintainer (me), it still doesn't
have anyone that *cares* about it. But I'm willing to help solve your
report & release a new version with the fix if it's easy for me.

It now has a Git repository at:

    http://github.com/avar/YAML-Syck

If your report is a patch that fixes a problem, great. Please remake
the patch against Git by forking that repo and sending me a pull
request on GitHub (or an update to this bug if you prefer
git-format-patch(1) or some other repo provider..). Make sure to
include a test for what you fixed.

If your report is some code that fails (and you have a testcase for
it) a patch against the test suite to demonstrate that failure would
be very useful. It's OK if the test crashes and burns, see
Test::More's docs for how to make TODO tests that fail now, but
shouldn't. Even if it segfaults perl C<system $^X => qw/ -Mblib
-MYAML::Syck .../> or something like that and checking the return
value will do.

I'm making this a wish list item. patches welcome, but otherwise I don't see this getting fixed. 
Any fix would have to be fully backwards compatible, which I'm not sure this would be.

NOTE I also found that there's a leading space on references to duplicate items too. (&1)
