git_patchset_body needs patch generated with --full-index option to
detect split patches, meaning two patches which corresponds to single
difftree (raw diff) entry. An example of such situation is changing
type (mode) of a file, e.g. from plain file to symbolic link.
Add, in git_blobdiff, --full-index option to patch generating git diff
invocation, for the 'html' format output ("blobdiff" view).
"blobdiff_plain" still uses shortened sha1 in the extended git diff
header "index <hash>..<hash>[ <mode>]" line.
git_patchset_body and git_commitdiff (but not git_blobdiff) were adjusted
for the split patches in commit 6d55f05576851aedc7c53f7438c1d505c22ee78f

This patch fixes it.
