[PATCH 2/2] rebase -i: Preserve whitespace at beginning of commit header in $GIT_EDITOR

During "git rebase -i", when the commit headers are shown in the editor for action (pick/squash/etc), the whitespace (if any) at the beginning of commit headers are stripped out due to the use of "read shortsha1 rest" for reading the output of "git rev-list".

The missing beginning whitespace do not pose any harm but this could be annoying when you want to identify these commits to perform actions on, for example, rewording them to remove the beginning whitespace.

Not having the whitespace makes them hard to spot, and you have to rely on something like "git log --oneline" to identify them.

This patch:
	1. Ensures that the commit header shown in $GIT_EDITOR is
	   identical to actual commit header
	2. Add a test for it
