  patch_parse: correct parsing of patch containing not shown binary data. When not shown binary data is added or removed in a patch, patch parser is currently returning 'error -1 - corrupt git binary header at line 4'. Fix it by correctly handling case where binary data is added/removed. Signed-off-by: Gregory Herrero <gregory.herrero@oracle.com>
