```text
\break \bar "|:"
\set Score.skipTypesetting = ##t
```
The prototype implementation of the `\post` function proposed in [#5740], when 
applied to this `\set` command, makes the line break appear in the visual score.

** [issues:#1543] skipTypesetting doesn't behave well on its margins**

Skiptypesetting seems to override commands \*before\* its use, in particular 
the \break in the following snippet, which produces different results for 
2.12.3 and 2.13.51:
\version "2.12.3"
% \version "2.13.51"
bareSnippet = \{
  e'1
  \break \bar "|:"
  \set Score.skipTypesetting = \#\#t
  s1
  \break \bar "||"
  \set Score.skipTypesetting = \#\#f
  c'1
\}

\paper \{ line-width = 60\mm \}
\{
  \set Staff.instrumentName = \#\(lilypond-version\)
    \bareSnippet
  \} 

In 2.13.51 neither \break is shown: only 1 line of output is produced.
2.12.3 produces 3 lines as expected.
Neither version sees the first \bar \*before\* \skiptypesetting is in effect, 
although 2.12.3 sees the \break, and both versions see the second \bar, 
\*before\* skiptypesetting is cancelled.

Apparently, \skiptypesetting is overriding several commands before its own 
invocation, so presumably it is a timing issue;\).

It looks as though this was at least partially broken in 2.12.3 so I'm 
hesitantly calling it a regression.
