scripts/config: properly report and set string options
Currently, scripts/config removes the leading double-quote from string options, but leaves the trailing double-quote. Also, double-quotes in a string are escaped, but scripts/config does not unescape those when printing Finally, scripts/config does not escape double-quotes when setting string options. Eg. the current behavior: $ grep -E '^CONFIG_FOO=' .config CONFIG_FOO="Bar \"Buz\" Meh" $ ./scripts/config -s FOO Bar \"Buz\" Meh" $ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie' $ grep -E '^CONFIG_FOO=' .config CONFIG_FOO="Alpha "Bravo" Charlie" Fix those three, giving this new behavior: $ grep -E '^CONFIG_FOO=' .config CONFIG_FOO="Bar \"Buz\" Meh" $ ./scripts/config -s FOO Bar "Buz" Meh $ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie' $ grep -E '^CONFIG_FOO=' .config CONFIG_FOO="Alpha \"Bravo\" Charlie" Signed-off-by: "Yann E.
