pub const WORK_TREE_FLOOR: Duration;Expand description
How long a linked work tree has to have been left alone before it is offered at all.
A floor rather than a flag, and it is not the same decision as --older-than. That one is
off by default because a floor nobody asked for silently keeps directories they chose; this
one is on always because nobody chooses a work tree — the walk offers it, and a work tree
somebody used this morning is not a thing to put in front of them however clean it is.
The two compose rather than competing: the planner applies --older-than to every target
including these, so the effective floor is whichever is stricter, and there is still one
clock.
