Make arguments to builtins const Prior to this change, builtins would take their arguments as `wchar_t `. This implies that the order of the arguments may be changed (which is true, `wgetopter` does so) but also that the strings themselves may be changed, which no builtin should do. Switch them all to take `const wchar_t ` instead: now the arguments may be rearranged but their contents may no longer be modified. 2021-02-14 02:41:09 +00:00			`maybe_t<int> builtin_echo(parser_t &parser, io_streams_t &streams, const wchar_t **argv);`
