++
+The 'tformat:' format works exactly like 'format:', except that it
+provides "terminator" semantics instead of "separator" semantics. In
+other words, each commit has the message terminator character (usually a
+newline) appended, rather than a separator placed between entries.
+This means that the final entry of a single-line format will be properly
+terminated with a new line, just as the "oneline" format does.
+For example:

+---------------------
+$ git log -2 --pretty=format:%h 4da45bef \
+  | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
+4da45be
