+Expansion of ~ to $HOME is handled by the shell, not by any POSIX APIs.  
+
+Furthermore, UnixPath.GetFullPath() has not been documented as
+performing tilde expansion (it's missing docs entirely, actually, but
+that's missing the point).
+
+Finally, `~' is a valid filename character; `cd; touch ./~` is a
+perfectly valid set of commands to execute, and results in a file
+named `~' in your home directory, and I'd prefer not to contemplate
+how to disambiguate an actual file named `~' vs. `~' meaning $HOME,
+especially since UnixPath.GetFullPath() shouldn't be reading
+directories anyway (so there would be no way to perform any
+disambiguation without a severe performance penalty).
