But we have to worry about ',' in $me, which is $0, not
its basename.  Do you want me (Akim, not the variable)
to change me (the variable, not Akim; not that I am
immutable) to basename and use / in the sed command,
instead of ','?

# warnf_ FORMAT-STRING ARG1...
warnf_ ()
{
  warnf_format_=$1
  shift
  printf "$warnf_format_" "$@" | sed "s,^,$me: ," >&2
}
