Fix error in diff html rendering (#13191)

* Fix error in diff html rendering

Was missing an optional whitespace check in regex. Also noticed a rare case where diff.Type == Equal would be empty and thus get a newline attached. Fixed that too.

Fixes #13177

* Update services/gitdiff/gitdiff.go

Co-authored-by: zeripath <art27@cantab.net>

* Update gitdiff_test.go

* fmt
