commit 3ce64010f8ce3accc64eff312f31dc0d3c0fc9d1 Author: Daniel Kolesa <[email protected]> AuthorDate: 2023-03-20 16:42:59 +0000 Commit: Baptiste Daroussin <[email protected]> CommitDate: 2023-03-20 16:56:56 +0000 sh(1): fix history file write checking We cannot just compare histsizeval() against 0, since that returns a string pointer, which is always non-zero (non-null). The logic in sethistsize() initializes the history size to 100 with values that are non-number, and an empty string counts as that. Therefore, the only time we want to not write into history with HISTSIZE val set is when it's explicitly 0.
