Re: [PATCH] configurable format of email notifications

Updating my March 8, 2006 patch to the latest trunk.

I see that the latest script can include URLs with the messages.
I believe the URL enhancment does not conflict with this patch.

[[[
Fix issue #2499: configurable subject line in email notifications

* tools/hook-scripts/mailer/mailer.py
  (top doc string): Document that the lock/unlock logging reads
  paths from stdin.
  (global scope): Fail safely when the older Subversion library is
  detected.
  (OutputBase.make_subject): Format the subject line according to
  the subject_format parameter.
  (OutputBase.run): Accept an optional parameter which is a
  function to write the output with.
  (MailedOutput.write_nop): New function suppressing output when
  to_addr is empty. This enables a for_path negative match.
  (SMTPOutput.start): Return early on empty to_addr.
  (SMTPOutput.finish): Likewise.
  (StandardOutput): Derive from MailedOutput to share the message
  suppression logic in case of empty to_addr.
  (StandardOutput.__init__): Delete. I believe the ancestor's
  __init__ will be called automatically.
  (StandardOutput.start): Return early on empty to_addr. Display
  to_addr otherwise. This is useful in testing.
  (PipeOutput.start,
  PipeOutput.finish): Likewise.
  (PropChange.generate, Lock.generate, TextCommitRenderer.render):
  Compose the body of notification based on the body_format
  parameter.
  (TextCommitRenderer._render_list,
  TextCommitRenderer._render_diffs): Accept the write function
  parameter.
  (generate_content): Pass the body_format parameter to the commit
  renderer, along with the configuration and current group.
  (format_body): New function. Produces the text of the message
  body based on the configuration parameter body_format.
  (generate_list): Use a global static dictionary which is
  initialized depending on Subversion's version. (I could not
  emulate the "Replaced:" selection with the older Subversion).
  (Config.get): Ignore erroneous keys when expanding parameters.
  The complete value will remain unexpanded. Expand
  backslash-encoded newlines.
  (__main__.usage): Indicate values expected from standard input.
  (__main__): Fall back to the raw repoditory path when path
  canonicalization is not implemented.

* tools/hook-scripts/mailer/mailer.conf.example
  Set a restrictive default for_paths to show only changes
  matching user-defined groups. Comment on configuring
  subject_format and body_format.

* tools/hook-scripts/mailer/mailer-t1.output
  Add the new "To:" headers introduced by this patch. Adjust to
  this patch stripping subject lines. I kept the "Replaced:" line
  that is missing in the output produced with this patch because I
  consider this a deficiency in the patch, not in the expected
  output.

* tools/hook-scripts/mailer/mock-sendmail
  New file. This script shows parameters and standard input
  submitted to it. It is useful for testing actual emailing by
  setting mail_command. Add examples of user-defined groups and
  "negative match" groups.
