That's a "bug" (or, more correctly, a "lack of feature") in the
substitution parser; it doesn't honor escapes.

But, regardless, a better, more readable solution is to use a different
delimiter, something other than "/". For example:

	's|$|/IssueNavigator|'

Note, too, that you want to use a "$", not an "&", to denote "end of line"
in the regular expression.
