You do not need to worry. C-string problem is already solved, just
I haven't time to update string_algo yet.
In the boost::range rework, we have though about c-string support
and we came to a reasonable solution. While boost::range does not
directly support c-string, it is possible to use as_literal and
as_array adaptors which turn a c-string or c-array into a range.

String Algorithms will use as_literal internaly, so the c-string
support will remain intact from the user parspective. In addition
there will be an option for user, to supply c-array argument
using as_array adaptor.

Best regards,
Pavol
