obsstore: refactor v1 logic to fix 32 byte hash support
Refactor the v1 logic to determine the node parsing based on the flag.
Move the predecessor out of the fixed part and handle it like the other
nodes, removing most of the duplicated code for parsing 20/32 bytes
hashes.

" Changelog :
"
" 0.2.2 - Security fixes by removing custom tempfile creation
" - Removed need for DiffReviewCleanup/PatchReviewCleanup
" - Better command execution error detection and display
" - Improved diff view and folding by ignoring modelines
" - Improved tab labels display
"
" 0.2.1 - Minor temp directory autodetection logic and cleanup
"
" 0.2 - Removed the need for filterdiff by implementing it in pure vim script
" - Added DiffReview command for reverse (changed repository to
" pristine state) reviews.
" (PatchReview does pristine repository to patch review)
" - DiffReview does automatic detection and generation of diffs for
" various Source Control systems

" ===========================================================================
" This plugin allows single or multiple, patch or diff based code reviews to
" be easily done in VIM. VIM has :diffpatch command to do single file reviews
" but a) can not handle patch files containing multiple patches or b) do
" automated diff generation for various version control systems. This plugin
" attempts to provide those functionalities. It opens each changed / added or
" removed file diff in new tabs.
"
" Installing:
"
" For a quick start, unzip patchreview.zip into your ~/.vim directory and
" restart Vim.
"
" Details:
"
" Requirements:
"
" 1) VIM 7.0 or higher built with +diff option.
"
" 2) A gnu compatible patch command installed. This is the standard patch
" command on Linux, Mac OS X, *BSD, Cygwin or /usr/bin/gpatch on newer
" Solaris.
"
" 3) Optional (but recommended for speed)
"
" Install patchutils ( http://cyberelk.net/tim/patchutils/ ) for your
" OS. For windows it is available from Cygwin
"
" http://www.cygwin.com
"
" or GnuWin32
"
" http://gnuwin32.sourceforge.net/
"
" Install:
"
" 1) Extract the zip in your $HOME/.vim or $VIM/vimfiles directory and
" restart vim. The directory location relevant to your platform can be
" seen by running :help add-global-plugin in vim.
"
" 2) Restart vim.
"
" Configuration:
"
" Optionally, specify the locations to these filterdiff and patch commands
" and location of a temporary directory to use in your .vimrc.
"
" let g:patchreview_patch = '/path/to/gnu/patch'
"
" " If you are using filterdiff
" let g:patchreview_filterdiff = '/path/to/filterdiff'
"
"
" Usage:
"
" Please see :help patchreview or :help diffreview for details.
