Documentation

Parse the next variable reference at point.

The variable name could refer to either an environment variable, or a Lisp variable. The priority order depends on the setting of eshell-prefer-lisp-variables.

Its purpose is to call eshell-parse-variable-ref, and then to process any indices that come after the variable reference.
