Whats about the quite simple solution using sed? Actually the sed call
should be faster for many arguments and is reasonable fast for short
command lines.
func_exec_program ()
{
func_exec_program_core $(printf "\"%s\" " "$@" | sed \
-e 's/"--lt-[^"]*"[ \t]*//g' \
-e 's/^"\([^"]*\)"/\1/g' \
-e 's/[ \t]*"\([^"]*\)"/ \1/g'
)
}
