* Move lite_parse tests into a submodule
* Have lite_parse return partial parses when error encountered.
Although a parse fails, we can generally still return what was successfully
parsed. This is useful, for example, when figuring out completions at some
cursor position, because we can map the cursor to something more structured
(e.g., cursor is at a flag name).
Our own custom escaping unfortunately is far too simple to cover all cases.
Instead, the parser will now do no transforms on the args passed to an external
command, letting the process spawning library deal with doing the appropriate
escaping.
* refactor: expand_path and expand_ndots now work for any string.
* refactor: refactor test and add new ones.
* refactor: convert expanded to owned string
* feat: pub export of expand_ndots
* feat: add completion for ndots in fs-shell
* 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,
* Update run_external.rs
* Update run_external.rs
* Update run_external.rs
* Update run_external.rs

* Expand n dots early where tilde was also expanded.
* Remove normalize, not needed.
New function absolutize, doesn't follow links neither checks existence.
Renamed canonicalize_existing to canonicalize, works as expected.
* Remove normalize usages, change canonicalize.
* Treat strings as paths
* Making Commands match what UntaggedValue needs
* WIP
* WIP
* WIP
* Moved to expressions for conditions
* Add 'each' command to use command blocks
* More cleanup
* Add test for 'each'
* Instead use an expression block
