t/t4301-log-line-single-history.sh:
test the linear line of history.
t/t4302-log-line-merge-history.sh:
test the case that there are merges in the history.

Note that applying this with --whitespace=fix will make the tests
fail, as there are diffs contained which must preserve the SP TAB
sequence of context lines.
