in order to compile on rh7, need to remove “static” from signature of several prototype defs defined inside several functions in expressions.c.

Here is a helper function for non-interactive mode, e.g. “rpn 1 1 +”, which skips the first line (name of the command) and trims leading space from the output. This might be useful for piping output of a calculation…
