Leonhard Kipp eb3c2c9e76 Add comments to next LiteCommand (#2846) ... This commit applied adds comments preceding a command to the LiteCommands new field `comments`. This can be usefull for example when defining a function with `def`. Nushell could pick up the comments and display them when the user types `help my_def_func`. Example ```shell def my_echo [arg] { echo $arg } ``` The LiteCommand def will now contain the comments `My echo` and `It's much better :)`. The comment is not associated with the next command if there is a (or multiple) newline between them. Example ```shell echo 42 ``` This new functionality is similar to DocStrings. One might introduce a special notation for such DocStrings, so that the parser can differentiate better between discardable comments and usefull documentation.		2021-01-08 06:14:51 +13:00
