The test prepares a simple commit with HT on its log message lines, and makes sure that - formats that should or should not expand tabs by default do or do not expand tabs respectively, - with explicit --expand-tabs=<N> and short-hands --expand-tabs (equivalent to --expand-tabs=8) and --no-expand-tabs (equivalent to --expand-tabs=0) before or after the explicit --pretty=$fmt, the tabs are expanded (or not expanded) accordingly. The tests use the second line of the log message for formats other than --pretty=short, primarily because the first line of the email format is handled specially to add the [PATCH] prefix, etc. in a separate codepath (--pretty=short uses the first line because there is no other line to test).
