inconsistent docu and usage of Files.Locator error codes
|Assignee:||J. Templ||% Done:|
The Files documentation states that Files.Locator.This returns
NIL in case of an error and sets the result code in the receiver.
This differs from the implementation in HostFiles, which always returns a
new locator and sets the error code in the result. This implementation
uses the same pattern as Files.Directory.This and should be kept unchanged.
There are also several places in client modules (e.g. StdMenuTool.IncludeSub)
where error checking needs to be aligned with the specification.
