test-convert-git: Use ~ instead of ^ Solaris sh interprets ^ as pipe symbol and the test thus failed in strange ways. git can however use of HEAD~ instead of HEAD^.

transplant: Add trailing LF in tmp file for filtering Transplant filtering used a tmp file ending with the (stripped) commit message and thus no final LF. Text files not ending with LF is usually not used on Unix and is thus wrong ;-) The missing LF had bad consequences because Solaris sed chokes on unterminated input lines, so echo -n foo|sed 's,o,0,g' doesn't output anything, and the filter used in tests/test-transplant thus stripped the last (and only) line in the message away on solaris.
