Slashes don't escape properly

[Flynsarmy]

I have the following code

<pre lang="bash" line="1">rename "s/ ([a-z])/ \U\1\E/g" *.mkv</pre>

and on first page load it will show correctly as s/ ([a-z])/ \U\1\E/g" *.mkv however on second page load it shows as s/ ([a-z])/ U1E/g" *.mkv - notice the \ characters are now missing.. It appears this has something to do with the caching - I'm guessing the cache is loaded then the string is escaped again.

Actually the slashed are being stripped when saved into the postmeta cache.

Using wp_slash() highlighted post content when updating the postmeta resolves this.
