Documentation
Program to get the amount of free space on a file system.
We assume the output has the format of df.
The value of this variable must be just a command name or file name;
if you want to specify options, use directory-free-space-args.
A value of nil disables this feature.
Probably introduced at or before Emacs version 22.1.
