The C-calculator mode while construction has a syntax similar to
that of standard C. In interactive mode, any new input line will be
prompted with a ``n{...n\t
'' where `n' stands for the nesting
level and `\t
' for a tab. Recall that cmode-line-statement
means a string of semicolon separated C-calculator mode commands.
