Hi,

Currently, '\$' is used to try and provide an escaped '$'. In the context that
it appears, '$$' is the proper escape sequence. This gets interpreted as
'\${.}sharedir' where $. is an empty string, thus '\sharedir'. This is an
escape of an ordinary character that will be forbidden (or, in this case, take
on a different meaning) in future versions of regex(3).

Thanks,

Kyle Evans
