[PATCH v4 2/3] pretty: enable --expand-tabs by default for selected pretty formats

"git log --pretty={medium,full,fuller}" and "git log" by default prepend 4 spaces to the log message, so it makes sense to enable the new "expand-tabs" facility by default for these formats. Add --no-expand-tabs option to override the new default.

The change alone breaks a test in t4201 that runs "git shortlog" on the output from "git log", and expects that the output from "git log" does not do such a tab expansion. Adjust the test to explicitly disable expand-tabs with --no-expand-tabs.
