Suppose someone wanted to match `[foo]' in an earlier version of a
program and now wants to match `[foo][bar]' where `[foo]' and `[bar]'
are complicated expressions to be generated with help of `regexp-opt'.
The earlier version was obtained with `regexp-opt' producing
`\\[foo\\]'. For the new version `regexp-opt' would generate `\\[bar]'.
The resulting expression would read as `\\[foo\\]\\[bar]' which is
confusing since two different styles are involved. The user would have
to manually change `\\]' to `]' (or `]' to `\\]') to get a uniform
appearance.
