setup: stop packaging python3.dll and python3X.dll in the wheel distribution

Now that exewrapper is smart enough to find the DLLs it needs without help from
the build script, backout ed286d150aa8 and 2960b7fac966.  Note that this will
require deleting the build/lib.win-amd64-3.X directory to actually remove it
from the final wheel.

Most Mercurial commands accept various flags.

Flag names
==========

Flags for each command are listed in :hg:`help` for that command.
Additionally, some flags, such as --repository, are global and can be used with
any command - those are seen in :hg:`help -v`, and can be specified before or
after the command.

Every flag has at least a long name, such as --repository. Some flags may also
have a short one-letter name, such as the equivalent -R. Using the short or long
name is equivalent and has the same effect. The long name may be abbreviated to
any unambiguous prefix. For example, :hg:`commit --amend` can be abbreviated
to :hg:`commit --am`.

Flags that have a short name can also be bundled together - for instance, to
specify both --edit (short -e) and --interactive (short -i), one could use::

    hg commit -ei

If any of the bundled flags takes a value (i.e. is not a boolean), it must be
last, followed by the value::

    hg commit -im 'Message'

Flag types
==========

Mercurial command-line flags can be strings, numbers, booleans, or lists of
strings.

Specifying flag values
======================

The following syntaxes are allowed, assuming a flag 'flagname' with short name
'f'::

    --flagname=foo
    --flagname foo
    -f foo
    -ffoo

This syntax applies to all non-boolean flags (strings, numbers or lists).

Specifying boolean flags
========================

Boolean flags do not take a value parameter. To specify a boolean, use the flag
name to set it to true, or the same name prefixed with 'no-' to set it to
false::

    hg commit --interactive
    hg commit --no-interactive

Specifying list flags
=====================

List flags take multiple values. To specify them, pass the flag multiple times::

    hg files --include mercurial --include tests

Setting flag defaults
=====================

In order to set a default value for a flag in an hgrc file, it is recommended to
use aliases::

    [alias]
    commit = commit --interactive

For more information on hgrc files, see :hg:`help config`.

Overriding flags on the command line
====================================

If the same non-list flag is specified multiple times on the command line, the
latest specification is used::

    hg commit -m "Ignored value" -m "Used value"

This includes the use of aliases - e.g., if one has::

    [alias]
    committemp = commit -m "Ignored value"

then the following command will override that -m::

    hg committemp -m "Used value"

Overriding flag defaults
========================

Every flag has a default value, and you may also set your own defaults in hgrc
as described above.
Except for list flags, defaults can be overridden on the command line simply by
specifying the flag in that location.

Hidden flags
============

Some flags are not shown in a command's help by default - specifically, those
that are deemed to be experimental, deprecated or advanced. To show all flags,
add the --verbose flag for the help command::

    hg help --verbose commit
