Bug#1151565: RFS: git-diff-html/1.1-1 -- generate side-by-side HTML diff reports for Git repositories

[Lu Haoran]

Hi Daniel,

Thanks for the review and for uploading it to NEW.

I'll handle the three notes in the next upload after NEW processing: bump 
Standards-Version to 4.7.4, document the two-file compare in the man page, and 
sync the salsa main branch with upstream/latest.

Best regards,
Lu Haoran
