bug#27453: 25.1; vc/log-view.el log-view-message-re doesn't support newer Darcs log format

[Rohan Hart]

vc-darcs is the emacs package for darcs integration with vc.

If you wished to support very old versions of darcs then keep that complex match and put the new one before it. Not that I've tested that config - I just override the entire log-view-message-re as I don't use any of those other version control systems

thanks

Then perhaps it does make sense to add the regexp to log-view-message-re
after all.  The current definition is:

(defvar log-view-message-re
  (concat "^\\(?:revision \\(?1:[.0-9]+\\)\\(?:\t.*\\)?" ; RCS and CVS.
          "\\|r\\(?1:[0-9]+\\) | .* | .*"                ; Subversion.
          "\\|D \\(?1:[.0-9]+\\) .*"                     ; SCCS.
          ;; Darcs doesn't have revision names.  VC-darcs uses patch names
          ;; instead.  Darcs patch names are hashcodes, which do not appear
          ;; in the log output :-(, but darcs accepts any prefix of the log
          ;; message as a patch name, so we match the first line of the log
          ;; message.
          ;; First loosely match the date format.
          (concat "\\|[^ \n].*[^0-9\n][0-9][0-9]:[0-9][0-9][^0-9\n].*[^ \n]"
                  ;;Email of user and finally Msg, used as revision name.
                  "  .*@.*\n\\(?:  \\* \\(?1:.*\\)\\)?")
          "\\)$")

Is VC-darcs something else than darcs?  Or is that an Emacs package?
