"D.C. al Fine" best practice

[address@hidden]

Hi folks

I can imagine several ways of displaying / tweaking / formatting "Fine"
and "D.C. al Fine" markups. Probably the simplest might be:

\version "2.19.83"

melody = \relative c' {
  c4 d e f \bar "||" \mark \markup {Fine}|
  g8 g a f g g g4\fermata \bar "|." \mark \markup { "D.C. al Fine"}
}

\score {
  \melody
  \layout { }
}

According to my score reading and interpreting experience,
* the markups are usually set in bold letters an horizontally right-
aligned to the bar line;
* "Fine" should stay in the first bar on the first line as it is not a
rehearsal mark

As always I'm aiming to make use of Lilypond's great default engraving
capabilities the most possible with as few tweaks, "intransparent" lines
of code, and absolute positionings etc. as possible.

Which is your recommended "good" way? What's your experience?

TIA
Stephan
