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