"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 spaces
to fill to the next display column that is multiple of 8)
in the log message before showing it 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.
