Subject: Bug fix. Reset size information when clearing the history.
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=71c71e7690f8ff683bb436a468810ef34b4f31b5;p=linenoise.git

Bug fix. Reset size information when clearing the history.

Otherwise the next historyAdd will access freed memory, and crash.
