Why does the current implementation of parse-colon-path use
expand-file-name? The comment says "to expand "~", but the original
implementation in Emacs 27 didn't do that.
Bug#21454 only wanted to avoid mis-interpreting duplicate slashes in
the input path, but there's no need to collapse them, so I don't see
how the call to expand-file-name is at all necessary, and could
potentially change behavior in unintended ways. Am I missing
something?
