I think this is missing some

                                  ^^^

	$ echo "/fo'ba" | sed -e 's/'\''/'\''\'\'''\''/g' -e 's/.*/ '\''&'\''/'
	 '/fo'''ba'


Do I have a thinko or should it be this:

+		sed -e 's/'\''/'\''\\\'\'''\''/g' -e 's/.*/ '\''&'\''/'
		                   ^^
			(added for escaping ' outside single quotes)

leading to:

	$ echo "/fo'ba" | sed -e 's/'\''/'\''\\\'\'''\''/g' -e 's/.*/ '\''&'\''/'
	 '/fo'\''ba'


Well, I was unsure, so I've tested...


Without this change:

	$ ./git-am.sh --directory="fo'ba" /tmp/test/*
	Applying: abcdefg
	./git-am.sh: eval: line 471: unexpected EOF while looking for matching
	`''
	./git-am.sh: eval: line 472: syntax error: unexpected end of file
	Patch failed at 0001.
	When you have resolved this problem run "git am --resolved".
	If you would prefer to skip this patch, instead run "git am --skip".
	To restore the original branch and stop patching run "git am --abort".

And with this change:

	$ ./git-am.sh --directory="fo'ba" /tmp/test/*
	Applying: abcdefg
	Applying: asdgasfh

Have you forgotten to add the files prefixed with "am-test-5-" or is this
patch based on another one?

$ git ls-files t/t4252
t/t4252/am-test-1-1
t/t4252/am-test-1-2

t/t4252/file-1-0

Thanks and regards,
