  12 ## __mdw_addto VAR DIR PATH ...
  13 ##
  14 ## VAR is the name of a PATH-like environment variable (i.e., one which
  15 ## contains a sequence of pathnames separated by colons).  DIR is either `l'
  16 ## or `r'.  The PATHs are pathnames.  Those PATHs which correspond to
  17 ## existing directories but which aren't currently named in the variable are
  18 ## added to the left or right (depending on DIR) of VAR.  The relative order
  19 ## of PATHs added in the same invokation is the same as the order they
  20 ## appeared in PATHs: the DIR argument only affects which end of the VAR they
  21 ## get added to.
