[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: [e-mail]
        ReportedBy: [e-mail]

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.]

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.

Winhelp now uses richedit rendering, the bug looks fixed for me. Please,
retest.

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