[PATCH 2/7] t1300: add test for --replace-all with value_regex

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <dstolee@microsoft.com>

The --replace-all option was added in 4ddba79d (git-config-set: add more
options) but was not tested along with the 'value_regex' parameter.
Since we will be updating this option to optionally treat 'value_regex'
as a fixed string, let's add a test here that documents the current
behavior.
