Someone might want to use it to disable the case sensitivity search.

After Eli e-mail, i agree with the OP and you that would be more
consistent if '\cCa' disables case sensitive searches as '\cc\A' does.

In case that is difficult to implement, we might want to document
that the  slash trick just works for single characters.  Then, the user
would just use '\cca' which loks even simpler.
