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.
* Update dependencies
* Document the lexer and lightly improve its names
The bulk of this pull request adds a substantial amount of new inline
documentation for the lexer. Along the way, I made a few minor changes
to the names in the lexer, most of which were internal.
The main change that affects other files is renaming `group` to `block`,
since the function is actually parsing a block (a list of groups).
* Fix rustfmt
* Update lock
