"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.

Perform a tab expansion (replace each tab with enough number
of spaces to fill to the next display column that is
multiple of 8) in the log message before using the message
to show in the output.
++
+By default, tabs are expanded in pretty formats that indent the log
+message by 4 spaces (i.e. 'medium', which is the default, 'full',
+and "fuller'). `--no-expand-tabs` option can be used to disable
+this.
