How big a new pane should be.

One value with two spellings, not a size and a percentage. tmux takes both through {@code -l},
so there is no pair of fields to hold consistent and no "both were given" error to raise — the
Python sibling's {@code size}/{@code percentage} pair and the {@code ValueError} guarding it both
disappear.

tmux's own {@code -p} flag is never emitted. It is broken in 3.4, which reads the {@code -l}
argument while handling {@code -p} and fails with {@code size missing}; {@code -l 25%} produces the
same pane on every supported release.
