Properly wrap `kak_assert` into a do-while scope Expanding the `kak_assert` macro to either an `if` statement or nothing leads to issues when the macro is used in a conditional statement that doesn't use braces. Example: ncurses_ui.cc:476, in non debug mode, the macro will expand to an empty line, resulting in the `ungetch` call not being executed if the `ioctl` call succeeds (line 448). 2017-02-19 15:37:32 +01:00			`#define kak_assert(...) do { \`
