During the code review of a recent patch, it was noted that shell scripts
must not use 'which $cmd' to check the availability of the command $cmd.
The output of the command is not machine parseable and its exit code is
not reliable across platforms.

It is better to use 'type' to accomplish this task.

During code review of some patches, it was noted that redirection operators

Earlier, fba4f1 (grep -P: Fix matching ^ and $) fixed an ancient bug.  Add
some tests to protect the change from future breakages; a slightly broken
version of this was a part of the originally submitted patch.

When "git grep" is run with -P/--perl-regexp, it doesn't match ^ and $ at
the beginning/end of the line.  This is because PCRE normally matches ^
and $ at the beginning/end of the whole text, not for each line, and "git
grep" passes a large chunk of text (possibly containing many lines) to
pcre_exec() and then splits the text into lines.

This makes "git grep -P" behave differently from "git grep -E" and also
from "grep -P" and "pcregrep":

	$ cat file
	a
	 b
	$ git grep --no-index -P '^ ' file
	$ git grep --no-index -E '^ ' file
	file: b
	$ grep -c -P '^ ' file
	 b
	$ pcregrep -c '^ ' file
	 b

git-am.sh's check_patch_format function would attempt to preview
the patch to guess its format, but would go into an infinite loop
when the patch file happened to be empty.  The solution: exit the
loop when "read" fails, not when the line var, "$l1" becomes empty.

This works in both bash and dash:

    $ bash -c 'VAR=1 env' | grep VAR
    VAR=1
    $ dash -c 'VAR=1 env' | grep VAR
    VAR=1

But environment variables assigned this way are not necessarily propagated
through a function in POSIX compliant shells:

    $ bash -c 'f() { "$@"
    }; VAR=1 f "env"' | grep VAR
    VAR=1
    $ dash -c 'f() { "$@"
    }; VAR=1 f "env"' | grep VAR

Fix constructs like this, in particular, setting variables through
test_must_fail.

Plain old $# works to count the number of arguments in

When the --use-client-spec is given to clone, and the clone
path is a subset of the full tree as specified in the client,
future submits will go to the wrong place.

Factor out getClientSpec() so both clone/sync and submit can
use it.  Introduce getClientRoot() that is needed for the client
spec case, and use it instead of p4Where().

Test the five possible submit behaviors (add, modify, rename,
copy, delete).

If --use-client-spec was given, set the matching configuration
variable.  This is necessary to ensure that future submits
work properly.

The alternatives of requiring the user to set it, or providing
a command-line option on every submit, are error prone.
