   6 # Uses a temporary patch to save local changes, then execute the given
   7 # command, and restore local changes from the saved patch.  In
   8 # essence, "stg-k pop" is a "stg pop -k" that works better, hence its
   9 # name.

  11 # CAVEATS:
  12 # - this script relies on the operation to run ignoring hidden
  13 # patches, so in 0.12 (where "stg push" can push an hidden patch)
  14 # "stg-k push" will fail midway, albeit with no information loss -
  15 # you'll just have to finish manually.  This is fixed in 0.13
  16 # - running this script to pop all patches in the stack fails, since
  17 # stg-unnew does not support this case.
