dst may or may not exist. In case it exists it might already be a symlink.
In neither case we should try to canonicalize dst, only its parent directory.

We were reporting "no match" when sorting something like "0 ". This is
because we don't distinguish between 0 and invalid lines when sorting.
For debug output we have to get this information back.
GNU seq does not support -t, but always outputs a newline at the end.
Therefore, our default for -t should be \n.
Also removes support for escape sequences (interpreting a literal "\n"
as a newline). This is not what GNU seq is doing, and unexpected.
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.
When a single directory is passed to ls in recursive mode, uutils ls
won't print the directory name

This commit fixes this minor inconsistency and adds corresponding test.
Closes#2254. We should only inherit global settings for keys when there
are absolutely no options attached to the key.
The default key (matching the whole line) is implicitly added only if no
keys are supplied.
Improved some error messages by including more context.
* 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
