[PATCH] gitweb: Fix bug in "blobdiff" view for split (e.g. file to symlink) patches

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.
