lock in editor:info-mixin

Locks or unlocks the editor for modifications. If an editor is locked, all modifications are blocked, not just user modifications.

See also is-locked?.

This method does not affect internal locks, as discussed in Locks.

• (send an-editor:info-mixin lock lock?) -> void
     lock? : boolean

  If lock? is #f, the editor is unlocked, otherwise it is locked.

  Uses run-after-edit-sequence to call lock-status-changed.
