rev-list: use hdr_termination instead of a always using a newline
When adding support for prefixing output of log and other commands using
--line-prefix, commit 660e113ce1
("graph: add support for
--line-prefix on all graph-aware output", 2016-08-31) accidentally
broke rev-list --header output.
In order to make the output appear with a line-prefix, the flow was
changed to always use the graph subsystem for display. Unfortunately
the graph flow in rev-list did not use info->hdr_termination as it was
assumed that graph output would never need to putput NULs.
Since we now always use the graph code in order to handle the case of
line-prefix, simply replace putchar('\n') with
putchar(info->hdr_termination) which will correct this issue.
Add a test for the --header case to make sure we don't break it in the
future.
