The visibility of spanners which end on the first note following a line break is controlled by the after-line-breaking callback ly:spanner::kill-zero-spanned-time.
For objects such as glissandos and hairpins, the default behaviour is to hide the spanner after a break; disabling the callback will allow the left-broken span to be shown.
Conversely, spanners which are usually visible, such as text spans, can be hidden by enabling the callback.

\paper {

\override Hairpin.to-barline = ##f
\override Glissando.breakable = ##t
% show hairpin
\override Hairpin.after-line-breaking = ##t
% hide text span
\override TextSpanner.after-line-breaking =
#ly:spanner::kill-zero-spanned-time
