tests: skip `test-wsgicgi.t` on MSYS

The test is attempting to set `PATH_INFO="/rev/\xe2\x80\x94"` into the
environment, which it does.  The problem is that when MSYS sees a leading '/' in
an environment variable, it thinks it's a unix filesystem path, so it "helpfully"
prepends the Windows path to the MSYS root directory before running a non-MSYS
process.  hgweb would then split this value on '/', so it would get 'C:' instead
of 'rev', and return a 400 since that isn't a valid web command.

I tried generating a *.bat file, but had trouble running that via `cmd.exe`
inside the test.  I also tried generating an equivalent *.py launcher that would
set the environment variables itself.  But there is no `os.environb` on Windows,
and the value was getting mangled when put into the script.  So, I give up.  If
it's encoding stuff on Windows, it's probably broken.

Some commands allow the user to specify a date, e.g.:

- backout, commit, import, tag: Specify the commit date.
- log, revert, update: Select revision(s) by date.

Many date formats are valid. Here are some examples:

- ``Wed Dec 6 13:18:29 2006`` (local timezone assumed)
- ``Dec 6 13:18 -0600`` (year assumed, time offset provided)
- ``Dec 6 13:18 UTC`` (UTC and GMT are aliases for +0000)
- ``Dec 6`` (midnight)
- ``13:18`` (today assumed)
- ``3:39`` (3:39AM assumed)
- ``3:39pm`` (15:39)
- ``2006-12-06 13:18:29`` (ISO 8601 format)
- ``2006-12-6 13:18``
- ``2006-12-6``
- ``12-6``
- ``12/6``
- ``12/6/6`` (Dec 6 2006)
- ``today`` (midnight)
- ``yesterday`` (midnight)
- ``now`` - right now

Lastly, there is Mercurial's internal format:

- ``1165411109 0`` (Wed Dec 6 13:18:29 2006 UTC)

This is the internal representation format for dates. The first number
is the number of seconds since the epoch (1970-01-01 00:00 UTC). The
second is the offset of the local timezone, in seconds west of UTC
(negative if the timezone is east of UTC).

The log command also accepts date ranges:

- ``<DATE`` - at or before a given date/time
- ``>DATE`` - on or after a given date/time
- ``DATE to DATE`` - a date range, inclusive
- ``-DAYS`` - within a given number of days from today
