  Modified files:
    bin/sh               cd.c 
  Log:
  Split updatepwd() into two smaller functions.  The first one, findpwd(),
  computes the new path and the second one, updatepwd(), updates the variables
  PWD, OLDPWD and the path used for the pwd builtin according to the new
  directory.  For a logical directory change, chdir() is now called between
  those two functions, no longer causing wrong values to be stored in PWD etc. if
  it fails.
