HelpBrowser: ' appears in HTML views

[dcoshea]

When I use HelpBrowser to view the PWB.HLP file from Microsoft BASIC PDS 7.x (not sure on the version, this was just a quick test) or various other contemporary products including a PWB.HLP file, the first topic that appears, "Microsoft Advisor", shows:

 ┌──Edit/Debug───────────────┐ ┌──Languages─────────┐ ┌──APIs─────────────┐
 │                           │ │                    │ │                   │
 │ ◄Programmer's WorkBench►  │ │ ◄C Language►       │ │ ◄OS/2 Overview►   │
 │ ◄CodeView►                │ │ ◄C Libraries►      │ │ ◄OS/2 API►        │

Note the ' shouldn't be there, and messes up the alignment. I suppose the ' is double escaped, or doesn't need to be escaped, or something.

Another file where ' appears is in EDIT.HLP from MS-DOS 6.22, in the "Repeat Last Find Command" topic.

This was seen with 98182a9 on Windows 7, with sources built using Visual Studio 2015 with SP3.
