Comment (by pedromendonca):

 = **Some additional considerations** =

 1. Adding a third parameter to `wp_sprintf()` is not possible, because the
 current second parameter is `...$args`, which has variable lenght and must
 be kept as the last parameter.

 2. A single `wp_sprintf()` can have multiple `%l` placeholders, with both
 `' and '`/`' or '`, so it doesn't make sense to set it function wide.


 = **The solution** =

 Currently `wp_sprintf()` supports `%l` placeholder that sets a list `' and
 '` type delimited.
 It's possible to add support for more placeholders:
 - `%l$o` - **$o** stands for **OR** - Outputs `' or '` delimiters
 - `%l$a` - **$a** stands for **AND** - Outputs `' and '` delimiters and is
 an alias for the default `%l`

 The solution should allow all the below placeholder types:
 - Normal: `%l$o`, `%l$a`, `%l` (alias for `%l$a`)
 - Numbered: `%2$l$o`, `%2$l$a`, `%2$l` (alias for `%2$l$a`)

 I've tested this successfully, I'll publishing a patch below for everyone
 interested in testing this.
