Simplify the logic of computing the file path parameters (the
directory, prefix, suffix, and number of random characters) for the
temporary file created by `mktemp`. This commits adds an `Options`
struct as a layer of indirection between the application logic and
`clap`, and a `Params` struct whose associated function is responsible
for determining the file path parameters from the `Options`. This is
an improvement because the previous code had some logic for
determining file path parameters in one place and some in another
place.
Show the "total" label in the "source" column or in the "target"
column if the "source" column is not visible.

Include the suffix in the error message produced by `mktemp` when
there are too few Xs in the template. Before this commit,
$ mktemp --suffix=X aXX
mktemp: too few X's in template 'aXX'
After this commit,
$ mktemp --suffix=X aXX
mktemp: too few X's in template 'aXXX'
This matches the behavior of GNU `mktemp`.
Correct the error message when the template argument contains a path
separator in its suffix. Before this commit:
$ mktemp aXXX/b
mktemp: too few X's in template 'b'
After this commit:
$ mktemp aXXX/b
mktemp: invalid suffix '/b', contains directory separator
This error message is more appropriate and matches the behavior of GNU
mktemp.
Correct the error message produced by `mktemp` when `--tmpdir` is
given and the template is an absolute path:
$ mktemp --tmpdir=a /XXX
mktemp: invalid template, '/XXX'; with --tmpdir, it may not be absolute
On Android and macOS all/some tests for stdin fail with:
`cannot stat '-': No such file or directory`
Apparently the `/dev/stdin` redirect workaround doesn't work for
these targets.
Update `chown` to allow setting the owner of a file to a numeric user
ID regardless of whether a corresponding username exists on the
system.
For example,
$ touch f && sudo chown 12345 f
succeeds even though there is no named user with ID 12345.
Fixes#3380.
Correct the error that arises from a path separator in the prefix
portion of a template argument provided to `mktemp`. Before this
commit, the error message was incorrect:
$ mktemp -t a/bXXX
mktemp: failed to create file via template 'a/bXXX': No such file or directory (os error 2) at path "/tmp/a/bege"
After this commit, the error message is correct:
$ mktemp -t a/bXXX
mktemp: invalid template, 'a/bXXX', contains directory separator
The code was failing to check for a path separator in the prefix
portion of the template.
