Merge branch 'ds/config-literal-value'
Various subcommands of "git config" that takes value_regex learn the "--literal-value" option to take the value_regex option as a literal string. * ds/config-literal-value: config doc: value-pattern is not necessarily a regexp config: implement --fixed-value with --get* config: plumb --fixed-value into config API config: add --fixed-value option, un-implemented t1300: add test for --replace-all with value-pattern t1300: test "set all" mode with value-pattern config: replace 'value_regex' with 'value_pattern' config: convert multi_replace to flags
