Another use of approach a) is bash (which currently does not use
gnulib), but there are things to be aware of.  For example, for years,
readline had a bug on cygwin, where MB_CUR_MAX == 1, but
mbslen takes into account non-printing characters while
strlen does not, so an escape character embedded in a string
(common for bash prompts handed to readline) was being
mishandled when the code didn't  consistently stick with
approach a) vs. b).
