Two points here. For a list L,
 
 * "varnames(L)[i]" now works OK in git; and
 
 * The alternative "varname(L[i])" now also works.
 
 The first fix was just a matter of trivially generalizing something.
 The second was kinda subtle: varname() required the ID number of a series,
 while what you get from "L[i]" is an actual series, not its ID number. Now
 varname() accepts either an ID number or a series itself.
