parsePatch combines patches from multiple files into a single IUniDiff when there is no "Index" line #135
Description
parsePatch() in case of multiple files works well if the diff data for each file is preceeded by the "Index" line. In the absence of this "Index" line all patches are collapsed against the first file.
Since the "Index" line is optional, I would expect the below to work
Example: Pass the below diff string to parsePatch(). It is expected to return an array of 3 IUniDiff objects (each with 1 patch) for the 3 files. Instead it returns 1 IUniDiff object with 3 patches
