PR/471: Daiki Ueno: Delay interpreting arginp until we've processed our startup files (which can change the NLS environment). 2. Fix type of read in prompt confirmation (eg. rmstar) (David Kaspar). 3. Fix out of bounds read (Brooks Davis) (reproduce by starting tcsh and hitting tab at the prompt). 4. Don't play pointer tricks that are undefined in modern c (Brooks Davis).
