edit.c: In function ‘exec_edit’:
edit.c:432:25: warning: this ‘for’ clause does not guard... [-Wmisleading-indentation]
432 | for (i = 0 ; i < num && Zcol >= 1 ; i ++)
| ^~~
edit.c:434:33: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘for’
434 | Zcol -= 1;
| ^~~~
このwarningは今はちょっと置いとく。多分バグな気がするけど。
