tests: replace "cp -r" with "cp -R"
The POSIX documentation about "cp" [1] says:
....
RATIONALE
....
Earlier versions of this standard included support for the -r option to
copy file hierarchies. The -r option is historical practice on BSD and
BSD-derived systems. This option is no longer specified by POSIX.1-2008
but may be present in some implementations. The -R option was added as a
close synonym to the -r option, selected for consistency with all other
options in this volume of POSIX.1-2008 that do recursive directory
descent.
The difference between -R and the removed -r option is in the treatment
by cp of file types other than regular and directory. It was
implementation-defined how the - option treated special files to allow
both historical implementations and those that chose to support -r with
the same abilities as -R defined by this volume of POSIX.1-2008. The
original -r flag, for historic reasons, did not handle special files any
differently from regular files, but always read the file and copied its
contents. This had obvious problems in the presence of special file
types; for example, character devices, FIFOs, and sockets.
....
....
Issue 6
The -r option is marked obsolescent.
....
Issue 7
....
The obsolescent -r option is removed.
....
(No "Issue 8" yet)
Therefore it's clear that "cp -R" is strictly better than "cp -r".
The issue was discovered when running tests on OS X after 0d87b1caed92.

Multiple pre-existing heads on the branch
-----------------------------------------
Pull bring content, but nothing on the current branch, we should not consider
pre-existing heads.
$ cd ../a
$ hg branch unrelatedbranch
marked working directory as branch unrelatedbranch
(branches are permanent and global, did you want a bookmark?)
$ echo B1 > B1
$ hg commit -Am B1
adding B1
$ cd ../c
$ hg up 'desc(L2)'
2 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg pull --rebase

There is two local heads and we pull a third one.
The second local head should not confuse the `hg pull rebase`.
$ hg up 'desc(R6)'
1 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ echo M1 > M1
$ hg commit -Am M1

$ cd ../a
