Subject: [PATCH 1/2] fix 6074

Fixed functionallity of re_write property.
Previous code coudn't work because there was "^"++FakeName line,
   but FakeName could be MatchPattern so this would fail.
I changed the behaviour to append "^" while storeing the re_write,
alias or script_alias proplist.

Also, I included one simple re_write property into test, to make sure
everything works correcty.
