Jim,

One of my favorite tricks is a pipe to fmt. Fmt will preserve leading
whitespace (well, it can be trickier than that since fmt tries to do
pharagraph indentation as well). To force one-column output, you only
need to do "fmt -1", which strictly speaking denotes one-CHARACTER output,
but fmt does the right thing.

So:

 		"card-number", "card-exp", "card-name", "card-address", "card-city",
 		"card-zip"

piped through "fmt -1" gives (at least on this linux machine):

		"card-number",
		"card-exp",
		"card-name",
		"card-address",
		"card-city",
		"card-zip"

Of course, you still have the problem about selecting the braced-in
regions without using the mouse. Perhaps another out-of-the-box approach
is to pipe your entire code through a C beautifier. "indent" has so
many options, I would be surprised if array initializers one-per-line
was not one of them.
