title: perforce: create a local backup of current pendinglist
body: <p>in perforce, i have a pending list with some changed files. now i want to revert to the base, but without loosing my changes, so i want to back them up somewhere. like saving the DIFFs of each file. at a later time, i want to restore those changes and continue my work.</p>
  
  <p>is this possible? if so, how?</p>
  
  <p>thanks!</p>
