>Description:
	When `#', `##', `%', or `%%' variable expansion fails to match
	the given pattern, and the expression is within double quotes,
	the remainder of the quoted string is discarded with no further.
	Further variable expansion or backquote parsing is not performed,
	nor is the remainder of the string retained.


>How-To-Repeat:
	$ x=foo.c
	$ echo "${x%.c} bar"
	foo bar 
	$ x=foo
	$ echo "${x%.c} bar"
	foo


>Fix:
	The quoted string can be broken up into two quoted strings separated
	by whitespace.  This won't work if the remainder of the string past
	the expansion is not supposed to be separated by a space.

	$ x=foo
	$ echo "${x%.c}" "bar"
	foo bar
