* Implement \n[.$] variable properly.Kaz Kylheku2014-09-151-1/+1
| | | | Make .$ correspond to the number of arguments in the macro call.
* Fix \n interpolation; implement while.Kaz Kylheku2014-09-151-0/+1
| | | | | | | | | | | | The \n interpolation was not working: not substituting the result. When this logic was added, then this was happening even during expression evaluation. The right fix seems to be that scan_expression function needs to suppress output! Implemented the .while operator. str_to_code needed to be fixed so it only bangs together up to four characters, so that we can recognize "while" as "whil". Hack hack! Introduced the V4 macro for four character codes.
