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.
