Thanks.
The intention is good, but see comments on this part in the patch
below.

I see a few other remaining issues in the code after this patch is
applied. If we are doing other fixes like these, we may want to fix
them as well:
- test_must_fail is used to run cvs; it shouldn't (instead of
saying "test_must_fail cvs ...", just say "! cvs ...").
- A shell function should begin like this: "shellfunc () {"
- Redirection should not have SP before the filename (i.e. ">out",
not "> out").
- It is OK to spell single-liner subshell like this:
( cd cvswork3 && ! cvs -f diff -N -u ) &&
...
but a multi-line subshell should start its first command on a
separate line, like this:
(
cd cvswork3 &&
cvs update foo
) &&
...
- quite a few "[cvswork$n]" comments are truncated to "[cvswork$n"
in the test titles.
> Chain all shell commands with && to detect all kinds of failure.
I think you missed the one in 'merge early [cvswork3] b3 with b1'
where a merge is done in a subshell; a failed merge is not detected.
This is another reason why I asked you not to mix different things
in a single patch; if this patch is rerolled to cover missing "&&"
that you missed, it needs to be re-reviewed for the "sed -i" fix we
review during this round again.

You replaced the original "find" that was perfectly correct with
"pipe to grep -v" which is more expensive. Why?
The file stores the lines to be counted; why is it called a "Count"?
As "check.list" is really the "expected list of files", it may want
to be renamed to "list.expected" or something like that. Then the
output from this "find" would naturally become "list.actual", i.e.
find "$sandbox" -name CVS -type d -prune \
-o -type f -print >"$WORKDIR/list.actual"
Even though you are comparing only the number of lines in the file
in this function, are they expected to name the same set of paths?
The other function check_end_full_tree used to compare only the
count, but you changed it to compare the actul names of paths, which
may be a more robust and correct test, so it might make more sense
to redefine $WORKDIR/list.{expect,actual} to be a sorted list of
paths relative to the top of the working tree and do something like
this:
(
cd "$sandbox" &&
find . -name CVS -type d -prune -o -type f -print
) | sed -e "s|^./||" | sort >"$WORKDIR/list.actual"
and make sure "$WORKDIR/list.expect" is also sorted. Then you can
lose the "wc -l" based check from here and compare the list of
paths.

It is probably easier for a later patch to fix the indentation, if
these new lines followed the existing indentation.

You can say "git ls-tree --name-only -r" and lose the sed.
