[PATCH v4 1/6] config: fix typo in variable name

["Matthew Rogers via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Matthew Rogers <mattr94@xxxxxxxxx>

In git config use of the end_null variable to determine if we should be
null terminating our output.  While it is correct to say a string is
"null terminated" the character is actually the "nul" character, so this
malapropism is being fixed.
