== Description

If present, this function returns a string representing the user (which may be empty). Otherwise it returns an empty string. Any percent‐escapes in the string are decoded first.

----
== Complexity
Linear in `this‐>user().size()`.

== Exception Safety
Calls to allocate may throw.

== BNF
[,cpp]
----
userinfo    = user [ ":" [ password ] ]

user        = *( unreserved / pct-encoded / sub-delims )
password    = *( unreserved / pct-encoded / sub-delims / ":" )
