* Include `]` in a list by making the first character after the `[` or
`[^`. At any other place, `]` ends the list.
* Include `^` in a list by placing anywhere except first after the
`[`.
* Some examples of character lists:
`[a-d]` Matches any one of `a`, `b`, `c`, or `d` but not `ä`;
`[^a-d]` Matches exactly one character other than `a`, `b`, `c`,
or `d`;
`[0-9a-fA-F]` Matches exactly one hexadecimal digit;
`[a-]` Matches either `a` or `-`;
`[][]` Matches either `]` or `[`;
`[^]]` Matches exactly one character other than `]`;
`[]^]` Matches either `]` or `^`; and
`[^-]` Matches exactly one character other than `-`.
Beware that ranges in lists may include more than you expect:
Beware that a range must be specified from low value to high
value: `[z-a]` does not match any character at all, preventing the
entire glob from matching.
* Note that unlike typical Unix shell globs, wildcards (`*`, `?`,
and character lists) are allowed to match `/` directory
separators as well as the initial `.` in the name of a hidden
file or directory.
White space means the ASCII characters TAB, LF, VT, FF, CR, and SPACE.
Note that this does not include any of the many additional spacing
characters available in Unicode, and specifically does not include
U+00A0 NO-BREAK SPACE.
Because both LF and CR are white space and leading and trailing spaces
are stripped from each glob in a list, a list of globs may be broken

* Include `^` in a list by placing anywhere except first after the
`[`.
* Beware that ranges in lists may include more than you expect:
`[A-z]` Matches `A` and `Z`, but also matches `a` and some less
obvious characters such as `[`, `\`, and `]` with code point
values between `Z` and `a`.
* Beware that a range must be specified from low value to high
value: `[z-a]` does not match any character at all, preventing the
entire glob from matching.
