New in 2020.06:
+ SPECIAL NOTES:
+ Results of `dir` routine called with dirty base path are presented
as cleaned up for some paths (like `///` or `a/../a`) unlike
before. While compatibility with most of other cases is preserved
and no ecosystem fallout was observed, be cautious of the possible
observable changes if the code does not clean dirty paths using `cleanup` method.
+ Since this release, when you start Raku with "-" as a single positional parameter, it
will now check if STDIN is connected to a terminal. If it is, then
the REPL will be started, rather than appearing to freeze waiting
for the user to enter something and issue an EOF. If STDIN is *not*
connected to a terminal, then Raku will read from STDIN and process
that as the source of a program.
+ The `run` routine, `Proc.spawn` and `Proc::Async.new` are
extended with a new argument `:$win-verbatim-args` defaulting to
`False`. If the argument is left off or set to False, the
arguments are quoted according to the Microsoft convention. This
is identical to Rakus previous behavior and thus backwards
compatible. When passing True the passed arguments are
concatenated with a single space. No other processing takes
place. This allows to manually quote the arguments as necessary.
+ Changes:
+ Support verbatim argument handling for `Proc` [709941c6][9a75738f]
+ Signatures of `slurp` and `spurt` routines not accepting redundant arguments is
now compile time error rather than run-time one [22f43444]

+ The `rotate` method now returns `Seq` instead of `List` [4b501bd4]
+ Add CACHEDIR.TAG to mark cache dirs as cache [37646b86][c3bdb617][ef90599e]
+ Improve GNU C++ name mangling [4f672c27]
+ Make `Instant.raku` output simpler [c0b5fb28]
+ Improve smartmatching against `Mu`/`Any`/`Junction` types

+ Fixes:
+ Fix code objects created BEGIN time EVAL getting lost in precompilation [537f8877][169f63d9]
