largefiles: avoid unnecessary creation of .hg/largefiles when opening lfdirstate

Previously, the directory '.hg/largefiles' would always be created if it didn't
exist when the lfdirstate was opened.  If there were no standin files, no
dirstate file would be created in the directory.  The end result was that
enabling the largefiles extension globally, but not explicitly adding a
largefile would result in the repository eventually sprouting this directory.

Creation of this directory effectively changes readonly operations like summary
and status into operations that require write access.  Without write access,
commands that would succeed without the extension loaded would abort with a
surprising error when the extension is loaded, but not actively used:

  $ hg sum -R /tmp/thg --config extensions.largefiles=
  parent: 16541:00dc703d5aed
   repowidget: specify incoming bundle by plain file path to avoid url parsing
  branch: default
  abort: Permission denied: '/tmp/thg/.hg/largefiles'


This change is simpler than changing the callers of openlfdirstate() to use the
'create' parameter that was introduced in ae57920ac188, and probably how that
should have been implemented in the first place.

PatchReview Introduction                                  *patchreview-intro*

The Patch Review plugin allows easy single or multipatch code or diff reviews.

It opens each affected file in the patch or in a workspace diff in a diff view
in a separate tab.

VIM provides the |:diffpatch| and related commands to do single file reviews
but can not handle patch files containing multiple patches as is common with
software development projects. This plugin provides that missing
functionality.

It also improves on |:diffpatch|'s behaviour of creating the patched files in
the same directory as original file which can lead to project workspace
pollution.

It does automatic diff generation for various version control systems by
running their diff command.

PatchReview Options                                     *patchreview-options*

  g:patchreview_patch = {string}
      Optional path to patch binary. PatchReview tries to locate patch on
      system path automatically. If the binary is not on system path, this
      option tell PatchReview the full path to the binary.  This option, if
      specified, overrides the default patch binary on the path.

    examples:
        (On Windows with Cygwin) >
           let g:patchreview_patch = 'c:\\cygwin\\bin\\patch.exe'
<
        (On *nix systems) >
           let g:patchreview_patch = '/usr/bin/gpatch'
<

  g:patchreview_filterdiff = {string}
      Optional path to filterdiff binary. PatchReview tries to locate
      filterdiff on system path automatically. If the binary is not on system
      path, this option tell PatchReview the full path to the binary.  This
      option, if specified, overrides the default filterdiff binary on the
      path.

     examples:
        (On Windows with Cygwin)
>
           let g:patchreview_filterdiff = 'c:\\cygwin\\bin\\filterdiff.exe'
<
        (On *nix systems)
>
           let g:patchreview_filterdiff = '/usr/bin/filterdiff'

PatchReview Usage                                          *patchreview-usage*
                                                                *:DiffReview*

  :DiffReview

    Perform a diff review in the current directory under version control.
    Currently supports Mercurial (hg), Subversion (svn), CVS, Bazaar (bzr) and
    Monotone.

                                                                *:PatchReview*

  :PatchReview patchfile_path [optional_source_directory]

    Perform a patch review in the current directory based on the supplied
    patchfile_path. If optional_source_directory is specified, patchreview is
    done on that directory. Otherwise, the current directory is assumed to be
    the source directory.

    Only supports context or unified format patches.
