[Bug 10445] New: winhelp.exe problem displaying help file, related to LF / CR-LF end-of-line issue?

http://bugs.winehq.org/show_bug.cgi?id=10445

           Summary: winhelp.exe problem displaying help file, related to LF
                    / CR-LF end-of-line issue?
           Product: Wine
           Version: 0.9.49.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: wine-programs
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: markk(a)clara.co.uk


Hi,

The winhelp.exe program supplied with Wine appears to have a problem displaying
parts of some help files correctly. This is perhaps due to failing to recognise
a linefeed (LF) as being equivalent to CR/LF?

Instead of moving to the beginning of the next line, the next line is displayed
below and to the right of the rightmost character of the previous line.
Furthermore, if the text would extend past the right window border, each
subsequent character is displayed on a new line.

For example, consider the following text (where | denotes the right border):
---
this is a test               | 
of the Wine winhelp          |
program.                     |
---
That would actually be displayed as something like:
---
this is a test               |
              of the Wine win|
                            h|
                            e|
                            l|
[etc.]
---


Instructions to replicate the problem:
1. Go to http://www.atmel.com/products/pld/forms/splash.asp
2. Click the link to download the WinCUPL installer
3. Run the installer
4. After installation completes, use the Wine winhelp.exe to open the file
WinCupl/CUPLREF.HLP in the directory which the package was installed to.
5. In the Contents displayed, click on "2.2.1 Example 1 - Simple Gates"
6. Scroll down past the picture to the GATES.PLD text

I've traced winhelp renderer - it is NOT a CR/LF issue. Instead, it is a TAB
problem.
The code is smth. like:
<text1><LF><TAB><text2><LF><TAB><text3><LF><TAB>....

which is currently rendered as

text1
         text2
                  text3


Really I do not know why THIS CASE should be rendered as:

    text1
    text2
    text3

But it should, as native winhlp32 displays text correctly.

Yes, the problem appears to be fixed now (testing with Wine 1.1.0).
