trimhtml's Issues

preserveTags default true!

preserveTags default true!

I want Strip HTML tags, must preserveTags set false.
Please, update README.md

Newlines are not preserved

First of all, thank you for creating this package 👍

The current implementation removes newlines from the output, which can produce an incorrect result. Is this the intended behavior? Here's a simple example where whitespace is important:

trimHtml(`
<pre>
  foo
  bar
</pre>
`);
// Output will be: "<pre>  foo  bar</pre>"
// Instead of: "<pre>\n  foo\n  bar\n</pre>"

'sufix' should be spelled 'suffix'

Options limit no work

node.js

html = trimHtml('abcdefghijk', {limit:5});
console.log(html );//{html:'abcdefghijk...',more:true}

limit no work.
