I wanted to follow the same logic of inserting a space for
other possible character pairs: ", ', `, <>, [], {}.

For example, inserting a quote character next to an existing quote
character could insert a space between them.

Anyway, the docstring of `insert-parentheses' says:

"If `parens-require-spaces' is non-nil, this command also inserts a space
before and after, depending on the surrounding characters."

What does "depending on the surrounding characters" mean, when applied
to other characters, can be interpreted differently.
