patch 9.0.2030: no max callback recursion limit Commit: https://github.com/vim/vim/commit/47510f3d6598a1218958c03ed11337a43b73f48d Author: Christian Brabandt <cb@256bit.org> Date: Sun Oct 15 09:56:16 2023 +0200 patch 9.0.2030: no max callback recursion limit Problem: no max callback recursion limit Solution: bail out, if max call recursion for callback functions has been reached. This checks the 'maxfuncdepth' setting and throws E169 when a callback function recursively calls itself. closes: #13337 closes: #13339 Signed-off-by: Christian Brabandt <cb@256bit.org>
