convert fresh repo and also check localtimezone option

NOTE: This doesn't check all time zones -- it merely determines that
the configuration option is taking effect.

An arbitrary (U.S.) time zone is used here.  TZ=US/Hawaii is selected
since it does not use DST (unlike other U.S. time zones) and is always
a fixed difference from UTC.

This choice is limited to work on Linux environments. At least on
FreeBSD 11 this timezone is not known. A better choice is
TZ=Pacific/Johnston. On Linux "US/Hawaii" is just a symlink to this
name and also it is known on FreeBSD and on Solaris.

Test transcoding CVS log messages (issue5597)
=============================================

To emulate commit messages in (non-ascii) multiple encodings portably,
this test scenario writes CVS history file (*,v file) directly via
python code.

Commit messages of version 1.2 - 1.4 use u3042 in 3 encodings below.

|encoding  |byte sequence | decodable as:      |
|          |              | utf-8 euc-jp cp932 |
+----------+--------------+--------------------+
|utf-8     |\xe3\x81\x82  |  o      x     x    |
|euc-jp    |\xa4\xa2      |  x      o     o    |
|cp932     |\x82\xa0      |  x      x     o    |
