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.

$ hg help qrefresh
hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...
update the current patch
If any file patterns are provided, the refreshed patch will contain only
the modifications that match those patterns; the remaining modifications
will remain in the working directory.
If -s/--short is specified, files currently included in the patch will be
refreshed just like matched files and remain in the patch.
If -e/--edit is specified, Mercurial will start your configured editor for
you to enter a message. In case qrefresh fails, you will find a backup of
your message in ".hg/last-message.txt".
hg add/remove/copy/rename work as usual, though you might want to use git-
style patches (-g/--git or [diff] git=1) to track copies and renames. See
the diffs help topic for more information on the git diff format.
Returns 0 on success.
options ([+] can be repeated):
-e --edit invoke editor on commit messages

-u --user USER add/update author field in patch with given user
-D --currentdate add/update date field in patch with current date
