[ale] C++ "not all control paths return a value"

[Jim Popovitch]

Since your func is defined as retuning a string, that warning is
alerting you that parts of your code don't return a string.
Specifically if the variable "name" contains a ":" but never a "\" your
func will return without a valid return value.
