Issue #7585: use tab between components in unified and context diff headers.
Instead of spaces between the filename and date (or whatever the string
is that follows the filename, if any) use tabs. This is what the unix
'diff' command does, for example, and difflib was intended to follow
the 'standard' way of doing diffs. This improves compatibility with
patch tools. The docs and examples are also changed to recommended that
the date format used be the ISO 8601 format, which is what modern diff
tools emit by default.
