Blender Version
Broken: blender-2.80.0-git.03bd024c077d-windows64

Short description of error
After deleting a particle edit, the filesize remains the same.
For particle systems with large amount of particles, this leads to massive filesize bloat that cannot easily be reversed.
The only way around it is to delete the Particle System and add it again with the same Particle Settings, but this is troublesome because particle settings relating to the object (ie, vertex groups and materials) need to be setup again in the particle settings.

Exact steps for others to reproduce the error

Create particle system (eg, hair)
set particle amount to something large like 300,000
in particle edit mode make some changes
save, observe filesize (around 100mb)
Delete Edit from particle system panel
save, observe filesize (doesn't reduce)

The particle edit data only seems to be cleaned up when you delete the particle system.

Not sure why that was assigned to me in the first place?

@Sergey think the whole psys->particles thing should be cleared out when we remove edited hairs? At least afaik when you add hairs, psys->particlesis NULL, until one start editing them…
