\tweak inside Lyrics - is tweaking LyricHyphens unsupported?

[Janek Warchoł]

Hi all,

recently David allowed \tweak to be used in Lyrics context, and
allowed to use additional parameter for modifying indirect grobs.
Armed with that, i hoped to achieve the result of this:

{ \repeat unfold 4 c'16 }
\addlyrics { The \once \override LyricHyphen #'minimum-distance = #4
peo -- ple that }

using \tweak.  To my surprise none of the following works correctly:

{ \repeat unfold 4 c'16 }
\addlyrics { The peo \tweak #'minimum-distance #4 -- ple that }

{ \repeat unfold 4 c'16 }
\addlyrics { The peo \tweak LyricHyphen #'minimum-distance #4 -- ple that }

{ \repeat unfold 4 c'16 }
\addlyrics { The \tweak LyricHyphen #'minimum-distance #4 peo -- ple that }

Am i doing something wrong or is what i want simply unsupported?

thanks in advance,
Janek
