- Use `unicode_segmentation` and `unicode_width` to determine proper `break_line` position.
- Keep track of total_width as suggested by @tertsdiepraam.
- Add unittest for ZWJ unicode case
Related to #2319.
Port argument parsing from getopts to clap.
The only difference I have observed is that clap auto-generates -h and
-V short options for help and version, and there is no way (in clap 2.x)
to disable them.
If we notice that we can represent all arguments as BigInts, take a
different code path. Just like GNU seq this means we can print an
infinite amount of numbers in this case.
* expr: support arbitrary precision integers
Instead of i64s we now use BigInts for integer operations. This means
that no result or input can be out of range.
The representation of integer flags was changed from i64 to u8 to make
their intention clearer.
* expr: allow big numbers as arguments as well
Also adds some tests
* expr: use num-traits to check bigints for 0 and 1
* expr: remove obsolete refs
match ergonomics made these avoidable.
* formatting

Instead of using a BufReader and reading each line separately,
allocating a String for each one, we read to a chunk. Lines are
references to this chunk. This makes the allocator's job much easier
and yields performance improvements.
Chunks are read on a separate thread to further improve performance.
This closes#2181.
`who --lookup` is failing with a runtime panic (double free).
Since `crate::dns-lookup` already includes a safe wrapper for `getaddrinfo`
I used this crate instead of further debugging the existing code in
utmpx::canon_host().
* It was neccessary to remove the version constraint for libc in uucore.
* ls: Implement total size feature
- Implement total size reporting that was missing
- Fix minor formatting / readability nits
* tests: Add tests for ls total sizes feature
* ls: Fix MSRV build errors due to unsupported attributes for if blocks
* ls: Add windows support for total sizes feature
- Add windows support (defaults to file size as block sizes related
infromation is not avialable on windows)
- Renamed some functions
