fix(nix/readTree): make nixFileName only match .nix extensions r/2218
Nix unfortunately has terrible escaping syntax: If something is an
escape sequence it does not know, like \0, it just swallows the
backslash and returns the second character (byte) as is (yes,
"\0" == "0" is true). This created the following bug in nixFileName
which should have resulted in at least a parse error: "(.*)\.nix" is
the same as "(.*).nix" which meant that nixFileName matched anything
that is at least 4 characters long and ends in "nix". This lead to
readTree creating double attributes when directories are involved or
attributes for non-nix files.
