The output formats of "git log" that indent the log message by 4
spaces have been updated to expand tabs by default in previous
steps, without a way to restore the original behaviour.
Introduce a new "--no-expand-tabs" option to allow this.
As the effect of options is cumulative,
$ git log [--pretty=medium] --no-expand-tabs
would not expand, while this invocation
$ git log --no-expand-tabs --pretty[=medium]
by virtue of having --pretty later on the command line, expands tabs
again.
We _could_ introduce --expand-tabs option as well, to allow
$ git log --pretty=email --expand-tabs
but we don't bother, as the output format that do not expand tabs by
default are mostly meant to transfer the contents as literally as
possible.
