## __mdw_addto VAR DIR PATH ...

## VAR is the name of a PATH-like environment variable (i.e., one which

## 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.
