This is version 3 of the patch series I sent back on 21 Mar 2014. I have addressed all feedback to date, updated the coding style, and added signed-off-by lines from Jeff Sipek for those commits that I have received an explicit approval from him (but only if I have not made any other change to that particular commit).

I have added two new patches:
* Patch 28/31 fixes coding style issues in t-061.sh.  I inserted it
before the new patch 29/31 since 29/31 copies t-061.sh as t-062.sh,
and by fixing the style issues in the origin it is easier to track the
changes.  This means that v2 patches 28 and 29 are now numbered 29 and
30.  Sorry about that.
* Patch 31/31 removes all use of "git log -p" in the test suite.

To see how the patches have evolved, you might find http://www.lysator.liu.se/~ceder/guilt-oslo-2014-v3/ useful. It displays diffs of all the patches between v2 and v3, in pdiffdiff output format.

Here is the original blurb for the series, slightly edited:

I recently found myself sitting on a train with a computer in front of me. I tried to use "guilt import-commit", which seemed to work, but when I tried to "guilt push" the commits I had just imported I got some errors. It turned out that "guilt import-commit" had generated invalid patch names.

I decided to fix the issue, and write a test case that demonstrated the problem.

One thing led to another, and here I am, a few late nights at a hotel and a return trip on the train later, submitting a patch series in 28 parts. Sorry about the number of patches, but this is what happens when you uncover a bug while writing a test case for the bug you uncovered while writing a test case for your original problem.

The patch series consists of:
 - A number of fixes to the test suite.
 - A number of bug fixes which I hope are non-controversial.  Most of
   the fixes have test cases.
 - Changed behavior: "guilt push" when there is nothing more to push
   now uses exit status 1.  This makes it possible to write shell
   loops such as "while guilt push; do make test||break; done".  Also,
   "guilt pop" when no patches are applied also uses exit status 1.
   (This aligns "guilt push" and "guilt pop" with how "hg qpush" and
   "hg qpop" has worked for several years.)
 - Changed behavior: by default, guilt no longer changes branch when
   you push a patch.  You need to do "git config guilt.reusebranch
   false" to re-enable that.  This patch sets the default value of
   guilt.reusebranch to true; it should in my opinion change to false
   a year or two after the next release.
 - The humble beginnings of a coding style guide.
A more detailed overview of the patches:
1. Some tests fail if "git config guilt.diffstat true" is in effect.
2-4. Some commands fail if run from a directory with spaces in its
     name.
5. "guilt new" had an overly restrictive argument parser.
6-8. guilt.diffstat could break "guilt fold" and "guilt new".
9-10. The test suite did not test exit status properly.
11. Remove pointless redirections in the test suite.
12-13. "guilt header" tried to check if a patch existed, but the check
        was broken.
14-16. Various parts of guilt tried to ensure that patch names were
       legal git branch names, but failed.
17-20. "guilt graph" failed when no patch was applied, and when a
       branch name contained a comma or a quote.
21-23. "git config log.decorate short" caused "guilt import-commit",
       "guilt patchbomb" and "guilt rebase" to fail in various ways.
24. Patches may contain backslashes, but various informative messages
    from guilt did backslash processing.
25-26. "guilt push" and "guilt pop" should fail when there is nothing
       to do.
28. Fix coding style problems in a test case.
27, 29. These two commits were things I intended to contribute a while
       back, when contributing the "Change git branch when patches are
       applied" change (commit 67d3af63f422).  These commits makes
       that behavior optional, and it defaults to being disabled, so
       that you can use both Guilt v0.35 (and earlier) and the current
       Guilt code against the same repo.  These commits add some code
       complexity, and you might want to skip them if you think the
       current behavior is better.
30. A coding style guide, with Emacs support.
31. Avoid using "git log -p".

This patch series is also available on http://repo.or.cz/w/guilt/ceder.git in the "oslo-2014-v3" branch. If you already have a copy of guilt, you should be able to fetch that branch with something like:

    git remote add ceder http://repo.or.cz/r/guilt/ceder.git
    git fetch ceder refs/heads/oslo-2014-v3:refs/remotes/ceder/oslo-2014-v3

A few of the regression/t-*.out files contain non-ASCII characters. I hope they survive the mail transfer; if not, please use the repo above to fetch the commits.
