Fix handling of quoted strings in the config file parse_string() adapts the string length to automatically remove quotation marks when copying the string. However, when calling string_ncopy_do() strlen(arg) used to be called again instead of using the adapted value. This e.g. led to wrong locale settings when using set commit-encoding = "UTF-8" and thus a slightly messed up display. Thanks to Gerfried Fuchs for reporting this.
