(command-line-bv) should never cause an "encoding-error", because it
should never try to decode the command line.
Users of (command-line) should catch a potential "encoding-error" and
handle it appropriately.

Well, you still need to provide (command-line) and (program-arguments)
functions compatible with existing code. I think the root of the
problem is that Guile calls scm_set_program_arguments() [feature.c:72]
early in initialisation, and this can fail messily.
I still think your proposed "solution" causes WAY more problems than it
claims to solve, though. What do Andy & Ludovic think?
