Definitely. I also noticed it after created this ticket.



However I think `Pathname.glob` makes sense for two reasons.
Firstly, I think `Pathname.glob` should have same interface as `Dir.glob`. For example, if they have the same interface, we can replace `Dir.glob` with `Pathname.glob` more easily.

```
# before
Dir.glob('*', base: 'path/to/dir')


# When I'd like to get pathnames:

# If they don't have the same interface, I should rewrite the whole code.
Pathname('path/to/dir').glob('*')

# If they have the same interface, I'll just replace `Dir` with `Pathname` only. I think it is more easily.
Pathname.glob('*', base: 'path/to/dir')
```


Secondly, I feel the `Pathname('path/to/dir')` is a subject in `Pathname('path/to/dir').glob('*')`, and `base: 'path/to/dir'` is not a subject in `Pathname.glob('*', base: 'path/to/dir')`. 
I guess a base directory is not a subject of the `glob` methods in many cases, so I'd like to use the keyword argument style in many cases.

What do you think?

Feature #14405: Add base option to Pathname.glob also

`Dir.glob` has `base` option since Ruby 2.5.
https://bugs.ruby-lang.org/issues/13056

However `Pathname.glob` does not have the option.
I would like to use `base` option with `Pathname` class.
But I feel `Dir.glob('*.rb', base: 'dir').map{|path|Pathname(path)}` is lengthy, so I'd like to add the option to `Pathname.glob`.

This patch adds the option to `Pathname.glob` also.

For example:

```
require 'pathname'

p Pathname.glob('lib/i*.rb', 0)                               # => [#<Pathname:lib/irb.rb>, #<Pathname:lib/ipaddr.rb>]
p Dir.glob('i*.rb', 0, base: 'lib')                           # => ["irb.rb", "ipaddr.rb"]
p Dir.glob('i*.rb', base: 'lib')                              # => ["irb.rb", "ipaddr.rb"]
p Pathname.glob('i*.rb', 0, base: 'lib')                      # => [#<Pathname:irb.rb>, #<Pathname:ipaddr.rb>]
p Pathname.glob('i*.rb', base: 'lib')                         # => [#<Pathname:irb.rb>, #<Pathname:ipaddr.rb>]
p Pathname.glob('i*.rb', base: Pathname('lib'))               # => [#<Pathname:irb.rb>, #<Pathname:ipaddr.rb>]
p Pathname.glob('i*.rb', base: Pathname(`pwd`.chomp) / 'lib') # => [#<Pathname:irb.rb>, #<Pathname:ipaddr.rb>]
p Pathname.glob('i*.rb', base: File.join(`pwd`.chomp, 'lib')) # => [#<Pathname:irb.rb>, #<Pathname:ipaddr.rb>]

Pathname.glob('i*.rb', foo: 'bar') rescue p $!                # => #<ArgumentError: unknown keyword: foo>
Pathname.glob('i*.rb', foo: 'bar') rescue p $!.backtrace      # => ["<...>/test.rb:13:in `glob'", "<...>/test.rb:13:in `glob'", "<...>/test.rb:13:in `<main>'"]
```


If the patch is OK, I'll do the follwoing TODOs.

- Add documentation
- Add tests to here. https://github.com/ruby/ruby/blob/d891056e3a6232163e99636cfcbb7bbfe1291404/test/pathname/test_pathname.rb#L1231-L1241
