The overrides fall into the ‘else’ case and then the tweaks are applied.
I’m not sure why this is changing all of the following note heads (bug?)
but I have a solution for your problem: Just tweak only if there is a
rhythmic-event.

\version "2.19.35"

bgr =
#(define-music-function (music) (ly:music?)
   (music-map
(lambda (mus)
  (cond
   ((or (music-is-of-type? mus 'rest-event)
(music-is-of-type? mus 'multi-measure-rest))
(make-music 'SkipEvent mus))
   ((music-is-of-type? mus 'rhythmic-event)
#{
  \tweak NoteHead.font-size #-2
  \tweak Accidental.font-size #-2
  #mus
#})
   (else
mus)))
music))

\new Staff <<
  \new Voice <<
\relative c' {
  <<
{
  c4 d e f~
  f g a b
}

\bgr {
  g a b c~
  \once \override TieColumn.tie-configuration = #'((0 . 1) (0 . -1))
  c d e f
}

oh, yes, thanks, I see. That code does look so well-written, but I guess
it would take quite a bit of study of the underlying concepts to
understand how to tweak it.

Intentional.  It's

commit 11a9e5701316d46d34993fadb85482282c9753cc
Author: David Kastrup

Issue 4500: Support chaining \tweak variant of overrides

Something like

{ \once \tweak color #red \tweak font-size 2 NoteHead
  2 c'2
}

previously failed to result in having both tweaks register.

(version 2.19.24) which made sense while \tweak could also be used as an
override, namely between

Issue 2929: Allow \tweak to act as a stand-in for \once\override

Making tweak optionally accept a grob specification instead of music
to tweak makes it compatible with the behavior of functions such as
\footnote and \shape, and actually serves to simplify their
implementation.

One slight complication occurs in lyrics mode, as demonstrated by the
change necessary to input/regression/lyric-tweak.ly: with

\tweak color #red reddish fish,

LilyPond tries an override for a grob named "reddish" and fails.
Tweaks in lyrics mode are highly unusual, have not been supported for
long, and their effect can usually better be accomplished in markup
mode instead.  The fix here is to write

\tweak color #red \markup reddish fish,

since LilyPond does not consider explicit markup a candidate for
conversion into symbols.  The same problem is inherent with other
commands using the same kind of symbol-list-or-music? interface, like
\footnote, \hide, \omit.

(version 2.17.6) and

commit 269d0c6d104c40f75e225f93459fd827f4065905
Author: David Kastrup 
Date:   Sat Jul 18 17:30:26 2015 +0200

Issue 4533: Stop the generic \tweak command from working as override

The problem with letting the generic \tweak command work as an override
is that the tweaking of lyric events becomes awkward since plain lyrics
are hard to distinguish from property names.

This renames the combined tweak/override command into \propertyTweak and
changes all callers requiring the combined functionality to call
\propertyTweak (or its Scheme equivalent) rather than \tweak.

The original issue allowing \tweak to act as an override was issue 2929.
The issue allowing tweaks to function in \lyricmode is issue 2543.

(version 2.19.25)

Now that only \propertyTweak does that, maybe \tweak should not do this
kind of chaining but leave it to \propertyTweak.

What should \tweak do then?  Just go forward with the tweak on override
(which achieves nothing)?  Give a warning instead (we don't generally
get one for non-effective tweaks)?  Silently ignore it?

Hmm, not at all sure what's going on in that file, it would be nice if
there were some simple tweak that pulled it off though...

Re: how to produce this symbol?

[Pierre Perol-Schneider]

I'm glad you liked it.
Just in case, re-readind it, one could think that trill elements look too
thick.
Here's another option:

\version "2.18.2"

\transpose c c'' {
  s2. r4 |
  dis8
  ^\markup {
\translate #'(-5 . 0)
\rotate #-45
\pattern #4 #X #0
%% Optional:
\scale #'(1 . .7)
\musicglyph #"scripts.trill_element"
  }
  e gis b
}

Cheers,
Pierre

HI Pierre,

Where are markup functions such as rotate and pattern documented?

Hairpin across line break

[Andrew Bernard]

When I have a hairpin across a line break, ending on a dynamic which is the 
very first note in the bar, the hairpin does not continue acorss the line as I 
would expect it to. If you extend to the next note, the hairpin continues.

How does one produce the broken hairpin at the start of the next line in this 
sort of case?

Setting Hairpin.to-barline has no effect (and I would not expect it to).

\version "2.19.35"

\relative c'' {
  \clef treble
  \time 1/4

  c c c c c c c_\f\> c c c \break
  c_\pp c c c c c c c c c 
}

  -\tweak to-barline ##f
