`read-from-minibuffer` is the function designed as the core of `read-string`,
`read-number`, `completing-read`, and friends.

If you want to write such a `read-<foo>` function, then
`read-from-minibuffer` is for you.

If you want to just read a *string*, then `read-string` is what you
should use.  It doesn't behave very differently from
`read-from-minibuffer`, but it makes your code's intentions more clear.
