This is not how patterns work in rc; The only way to get
* to match any characters is for it to appear LITERALLY
and UNQUOTED. Therefore, only

	~ foo.c *

will match, not

	bar='*.c'
	~ foo.c $bar

The only way to get around this is with an explicit eval
statement:

	eval ~ $1 $foo

will present $foo to rc as if it had been rescanned (which
it is, actually).

I find these quoting rules to be quite simple, actually. Duff
explains them quite well in the paper bundled with rc-1.2.
