For example, when running the following:
crates/nu-cli/src
nushell currently parses this as an external command. Before running the command, we check to see if
it's a directory. If it is, we "auto cd" into that directory, otherwise we go through normal
external processing.
If we put a trailing slash on it though, shells typically interpret that as "user is explicitly
referencing directory". So
crates/nu-cli/src/
should not be interpreted as "run an external command". We intercept a trailing slash in the head
position of a command in a pipeline as such, and inject a `cd` internal command.

* Fix --headerless option of to-csv and to-tsv
Before to-csv --headerless split the "headerfull" output on lines,
skipped the first, and then concatenated them together. That meant
that all remaining output would be put on the same line, without
any delimiter, making it unusable. Now we replace the range of the
first line with the empty string, maintaining the rest of the
output unchanged.
* Remove extra space in indentation of to_delimited_data
* Add --separator <string> argument to to-csv
This functionaliy has been present before, but wasn't exposed
to the command.
* Refactor InputStream and affected commands.
First, making `values` private and leaning on the `Stream` implementation makes
consumes of `InputStream` less likely to have to change in the future, if we
change what an `InputStream` is internally.
Second, we're dropping `Option<InputStream>` as the input to pipelines,
internals, and externals. Instead, `InputStream.is_empty` can be used to check
for "emptiness". Empty streams are typically only ever used as the first input
to a pipeline.
* Add run_external internal command.
We want to push external commands closer to internal commands, eventually
eliminating the concept of "external" completely. This means we can consolidate
a couple of things:
- Variable evaluation (for example, `$it`, `$nu`, alias vars)
- Behaviour of whole stream vs per-item external execution
It should also make it easier for us to start introducing argument signatures
for external commands,

1. Fixed a bug where `--all` wasn't showing files at the root directories.
2. More use of `Result`'s `map` and `map_err` methods.
3. Making tables be homogeneous so one can, for example, `get directories`.
Previously, if the user didn't have the appropriate permissions to execute the
binary/script, they would see "command not found", which is confusing.
This commit eliminates the `which` crate in favour of `ichwh`, which deals
better with permissions by not dealing with them at all! This is closer to the
behaviour of `which` in many shells. Permission checks are then left up to the
caller to deal with.
Mostly, making more use of `map` and `map_err` in `Result`. One benefit
is that at least one location had duplicated logic for how to map the
error, which is no longer the case after this commit.

The extra newline character makes it hard to use nu as part of an
external processing pipeline, since the extra character could taint the
results. For example:
```
$ nu -c 'echo test | xxd'
00000000: 7465 7374 test
```
versus
```
nu -c 'echo test' | xxd
00000000: 7465 7374 0a test.
```

This improves incremental build time when working on what was previously
the root package. For example, previously all plugins would be rebuilt
with a change to `src/commands/classified/external.rs`, but now only
`nu-cli` will have to be rebuilt (and anything that depends on it).
