patch 9.0.2058: tests: avoid error when no swap files exist Commit: https://github.com/vim/vim/commit/a36acb7ac444a789440dc30e0f04d5427069face Author: zeertzjq <zeertzjq@outlook.com> Date: Sat Oct 21 11:50:26 2023 +0200 patch 9.0.2058: tests: avoid error when no swap files exist Problem: tests: avoid error when no swap files exist Solution: use unlet! so that no error message is reported in case the variable does not exists When s:GetSwapFileList() does not find any swapfiles, it will return an empty list []. This means, that the variable 'name' will not be declared, cause the following unlet command to fail and causing a 1 sec delay on running the tests. So let's instead use the :unlet! command which simply skips reporting an error when the variable given as parameter does not exists. closes: #13396 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: zeertzjq <zeertzjq@outlook.com>
