patchgit-rebase--interactive.sh: fix trailing spaces on empty $todo

For someone who use editor that display trailing white spaces, issuing interactive rebase will print two empty lines at the end of rebase with the last line contains tab,

  #	However, if you remove everything, the rebase will be aborted.
  #
  #\t
  # Note that empty commits are commented out

The character "\t" in above example is white space tab.

The "make test" was run succesfully but I can't reproduce/test manually with non-empty $todo (I have no idea how to do it).

When issuing interactive rebase, git will open a text editor with list of commits to rebase and documentation on how to edit it. At the end of documentation it display,

  #	However, if you remove everything, the rebase will be aborted.
  #
  #\t
  # Note that empty commits are commented out

The "\t" is white space tab.

This commit remove the empty tab at the last two line.

While the issue may still be there, I think that the mid-term plan for the release after this cycle is to use the GSoC version of "rebase -i" that rewrites all the logic that produces the above in C, which has been cooking in 'pu', and hopefully we can see it or its reroll in 'next' soonish.

So please see if the issue is there, or if you find other new issues (as this is essentially an attempted faithful re-implementation), in the version on 'pu', and report/fix them in there if necessary.

Thanks.
