patch 8.0.1450: GUI: endless loop when stopping cursor blinking commit https://github.com/vim/vim/commit/1dd45fb4f3371f0256653b2186c8b4b3d26b3f41 Author: Bram Moolenaar <Bram@vim.org> Date: Wed Jan 31 21:10:01 2018 +0100 patch 8.0.1450: GUI: endless loop when stopping cursor blinking Problem: Endless loop when gui_mch_stop_blink() is called while blink_state is BLINK_OFF. (zdohnal) Solution: Avoid calling gui_update_cursor() recursively.
