[PATCH 0/3] Miscellanous cleanups around start_command/run_command callers

This is just to flush a queue of unrelated changes before they pile up. I found these while I reviewed start_command and run_command call sites.

Johannes Sixt (3):
  Simplify some instances of run_command() by using
    run_command_v_opt().
  diff.c: plug a memory leak in an error path
  Simplify some 'fprintf(stderr); return -1;' by using 'return error()'
