Mostly I don't think you need \partial measures.  You can just put a \bar
command in the middle of a measure to end a partial measure, with the next
partial measure starting right there.

{
  \partial 4
  c''4 |
  c''4 c'' c''
  \repeat volta 2 {
    c''4 |
    c''4 c'' c'' c'' |
    c''4 c'' c''
  }
  \alternative {
    {
      c''4 |
      c''4 c'' c''
      \bar "|"
    }
    {
      a'4 |
      a'4 a' a'
      \bar "|."
    }
  }
}

\partial has always been not recommended for use in the middle of the piece.
Warnings were added so that users would be aware of this recommendation.

Typically this happens only with songs where each lyric phrase begins on an
upbeat, in my experience.  In this case, you want to get one lyric phrase
per line, so you may want to make a voice with just spacer rests to
establish the layout.

I've attached a sample.
