wishlist: Add Generated-By header to bzr diff

[Jari Aalto]

FEATURE REQUEST

    Consider typical bzr diff output:

        === added file 'Makefile'
        --- Makefile 1970-01-01 00:00:00 +0000
        +++ Makefile 2007-08-05 21:38:10 +0000

    I propose that a "header" is added to the beginning of diff to announce
    that this diff/patch was generated byg bzr:

        Generated-by: bazaar <VERSION>
        === added file 'Makefile'
        --- Makefile 1970-01-01 00:00:00 +0000
        +++ Makefile 2007-08-05 21:38:10 +0000

    There <VERSION> is the current bzr version information.

FOR COMPARISION

    Here how git's diff output looks like:

    gt diff 46f19ba9fd4f5b7279102e78788089d3bbe02d73
