Function: remfunction (<f_1>, ..., <f_n>)

Function: remfunction (all) Unbinds the function definitions of the symbols <f_1>, ..., <f_n>. The arguments may be the names of ordinary functions (created by `:=` or `define`) or macro functions (created by `::=`).

`remfunction (all)` unbinds all function definitions.

`remfunction` quotes its arguments.

`remfunction` returns a list of the symbols for which the function definition was unbound. `false` is returned in place of any symbol for which there is no function definition.

`remfunction` does not apply to array functions or subscripted functions. `remarray` applies to those types of functions.

```(%o1)                                true
