Thanks. Done. (But deleting code is no glory...)

Description: unset the limit to line length in plain text files
 The 'TEXT_MAXLINELEN 300' constant is removed, as well as the test for long
 lines, in the 'textmagic' function, in kio/kio/kmimemagic.cpp.
 It made konqueror identify configuration files with long lines as files from
 unknown type.
 .
 The bug is still present in the KDE4 code. It has already been reported
 (http://bugs.kde.org/143100), but the report was closed.
 .
 This bugfix doesn't solve other errors in file detection (debian/rules files
 not detected as "make files", wrong reports of "Java code", "Objective-C
 code", "diff"...). (http://bugs.kde.org/116272)
 .
 Thanks to Darrell Anderson, Werner Joss and Richard J.M. Hill.

The 'unknown type' problem is solved.
For other problems, I'm opening another bug report:
http://bugs.trinitydesktop.org/show_bug.cgi?id=661
where we can summarize all our discoveries.

Here is my summary:
Konqueror wrongly recognizes some files as of type:
* diff (as stated here: http://bugs.kde.org/116272
* Java code (the gtkrc file type which is 'UTF-8 Unicode C++ program text')
* C++ header
* Objective-C code (/etc/apt/apt.conf)
* C source file (~/.gnome2/totem_config)

And it doesn't recognize other types
* email files with extension .eml are recognized as plain text and or not
  associated with mail programs.
* debian/rules files (debian source packages) are not always recognized as make
  files.

* Empty files without extension should be opened in text editors.
* Empty files with known extensions should be opened like other files
  (db.sqlite, if empty, can't be opened in kexi from konqueror)


Concerning text files which contains passwords:
* the string contains more than 301 characters: bug
* it contains control characters: data file (but it's astonishing)
