+--config-env=<name>=<envvar>::
+ Like `-c <name>=<value>`, give configuration variable
+ '<name>' a value, where <envvar> is the name of an
+ environment variable from which to retrieve the value. Unlike
+ `-c` there is no shortcut for directly setting the value to an
+ empty string, instead the environment variable itself must be
+ set to the empty string. It is an error if the `<envvar>` does not exist
+ in the environment. `<envvar>` may not contain an equals sign
+ to avoid ambiguity with `<name>` containing one.
++
+This is useful for cases where you want to pass transitory
+configuration options to git, but are doing so on OS's where
+other processes might be able to read your cmdline
+(e.g. `/proc/self/cmdline`), but not your environ
+(e.g. `/proc/self/environ`). That behavior is the default on
+Linux, but may not be on your system.

+Note that this might add security for variables such as
+`http.extraHeader` where the sensitive information is part of
+the value, but not e.g. `url.<base>.insteadOf` where the
+sensitive information can be part of the key.
