These two targets do produce real files; do not put them on .PHONY target

This patch simplifies Brian's fix for the recent regression by:

* eliminating the extra loop
* eliminating use of git rev-parse for parsing flags
* making use of the for opt idiom for the retained loop
* eliminating the redundant -- case

The patch has been tested with the tests in current maint.

This bug was disovered by someone on IRC when he tried to

while <branch> already existed. In that case the stash is dropped even
though it isn't applied on any branch, so the stash is effectively lost.

The test was missing some "&&" at the end of some lines and it
was wrong because, as the replacement refs were not fetched,
the commits from the parallel branch should not show up. This
was found by Elijah Newren.

This is fixed by checking that after the branch from HASH6 is
fetched, the commits from the parallel branch don't show up,
and then by fetching the replacement refs and checking that
they do show up afterwards.

POSIX wants shells to support both "N" and "$N" and requires them to yield
the same answer to $((N)) and $(($N)), but we should aim for portability
in a case like this, especially when the price we pay to do so is so
small, i.e. a few extra dollars.

On systems which have dash as /bin/sh, such as Ubuntu, the final
test (master@{n} for various n) fails with a syntax error while
processing an arithmetic expansion. The syntax error is caused by
using a bare name ('N') as a variable reference in the expression.

In order to avoid the syntax error, we spell the variable reference
as '$N' rather than simply 'N'.

Currently git-stash uses `git rev-parse --no-revs -- "$@"` to set its
FLAGS variable.  This is the same as `FLAGS="-- $@"`.  It should use
`git rev-parse --no-revs --flags "$@"`, but that eats any "-q" or
"--quiet" argument.  So move the check for quiet before rev-parse.

Recently, the 'stash show' functionality was broken for the case when a
stash-like argument was supplied.  Since, commit 9bf09e, 'stash show' when
supplied a stash-like argument prints nothing and still exists with a zero
status.  Unfortunately, the flaw slipped through the test suite cracks
since the output of 'stash show' was not verified to be correct.

Improve and expand on the existing tests so that this flaws is detected.

Some versions of cut do not cope well with lines that do not end in

I found this problem when t3404's "avoid unnecessary reset" failed
due to the "rebase -i" not avoiding updating the tested timestamp.

The ancient touch on Solaris 7 thinks that a decimal number supplied as
the first argument specifies a date_time to give to the files specified by
the remaining arguments.  In this case, it fails to parse '1' as a proper
date_time and exits with a failure status.  Workaround this flaw by
rearranging the arguments supplied to touch so that a non-digit appears
first and touch will not be confused.
