A nit-pick.. This doesn't seem to mention what happens when the function is called recursively. I assume it does the right thing, but the paragraph wording is organized around "saving" its value and it only explicitly mentions returning from the function as saving the variable's value. > command is executed, if a value for variable had previously been > saved, then after its outside value has been preserved, the > previous value and attributes of variable are restored, and the > -I, -N, and -x flags, and any initialization of the variable > requested on the local command line, are ignored.
