How to use the @atomist/slack-messages.escape function in @atomist/slack-messages

export function truncateCommitMessage(message: string): string {
    const title = (message || "").split("\n")[0];
    const escapedTitle = escape(title);

    if (escapedTitle.length <= 50) {
        return escapedTitle;
    }

    const splitRegExp = /(&(?:[gl]t|amp);|<.*?\||>)/;
    const titleParts = escapedTitle.split(splitRegExp);
    let truncatedTitle = "";
    let addNext = 1;
    let i;
    for (i = 0; i < titleParts.length; i++) {
        let newTitle = truncatedTitle;
        if (i % 2 === 0) {
            newTitle += titleParts[i];
        } else if (/^&(?:[gl]t|amp);$/.test(titleParts[i])) {
            newTitle += "&";

export function truncateCommitMessage(message: string, repo: any): string {
    const title = message.split("\n")[0];
    const escapedTitle = slack.escape(title);
    const linkedTitle = linkIssues(escapedTitle, repo);

    if (linkedTitle.length <= 50) {
        return linkedTitle;
    }

    const splitRegExp = /(&(?:[gl]t|amp);|<.*?\||>)/;
    const titleParts = linkedTitle.split(splitRegExp);
    let truncatedTitle = "";
    let addNext = 1;
    let i;
    for (i = 0; i < titleParts.length; i++) {
        let newTitle = truncatedTitle;
        if (i % 2 === 0) {
