Treat tab chars as advancing to the next tab stop rather than having a fixed
8-column width.
Also treat tab as a whitespace split target only when splitting on word
boundaries.
* feat: move unexpand to clap
* chore: allow muliple files
* test: add test fixture, test reading from a file
* test: fix typo on file name, add test for multiple inputs

Current implementation of the skip fields logic does not handle
multibyte code points correctly. It assumes each code point (`char`) is
one byte. If the skipped part of the input line has any multibyte code
points then this can cause fields not being skipped correctly (field
start index is calculated to be before it actually starts).
When converting to SI or IEC, produce values that align with the conventions
used by GNU numfmt.
- values > 10 are represented without a decimal place, so 10000 becomes 10K
instead of 10.0K
- when truncating, take the ceiling of the value, so 100001 becomes 101K
- values < 10 are truncated to the highest tenth, so 1001 becomes 1.1K

The flag makes 'sort' command ignore non-dictionary symbols
(non-alphanumeric and non-spaces). The only difference with GNU sort is
that it takes ALL alphanumeric symbols, not only ASCII ones.
.# Discussion
This commit adds support for a '-f'/'--file' option which reads "KEY=VALUE" lines from
a config (or ini) style text file and sets the corresponding environment key. This is
modeled after the same option in the `dotenv` and `godotenv` commands. Notably, this
commit does *not* add automatic loading of ".env" configuration files.
The environment variables set by reading the configuration file are set prior to any
unset (eg, `-u BAR`) or set (eg, `FOO=bar`) actions. Files are loaded in order with
later files overwriting any overlapping environment variables, then, unset actions (in
command line order) are executed, then, finally, set actions (in command line order)
are executed.

There was an issue with autoformat when the files had a different
number of columns in the first line. This commit fixes the issue and
extends the related test to cover this case.
Make at_line_start persist between printing each file. This fixes an
issue when numbering lines in the output and one of the input files
does not have a trailing newline.
FileMerger receives Lines Iterables of the pre-sorted input files
via push_file() It implements Iterator, which yields lines from the
input files in (merged) sorted order. If the input files are not sorted,
then the behavior is undefined.
Internally, FileMerger uses a
std::collections::BinaryHeap<MergeableFile>.
MergeableFile is an internal helper that implements Ord in a way that
BinaryHeap can use (note that we want smallest-first, but BinaryHeap
returns largest first, so MergeableFile::cmp() calls reverse() on
whatever compare_by() returns.
Made a new function sort_by(lines, compare_fns), which accepts a
list of compare_fns and calls lines.sort_by() with a closure that
calls each compare_fn in turn until one returns something other
than equal.
Default behavior ensures that String::cmp is the last element in the
compare_fns list (referred to as 'last resort' sorting by man sort).
Passing --stable (-s) turns this behaviour off.
Test cases provided for `sort --month` and `sort --month --stable`.
Instead of using numerals to denote individual cases, I used descriptive
case names. I also changed the extension for the expected output fixture
to match other tests.
I removed one redundant test and another unnecessary helper function.
The repetition of "foo" and "bar" made for difficult-to-read assertion failures
when hacking on `tail`. I think that having each line have unique contents makes
it a bit easier to parse.
