#8 Edit task add lot of CRs

[Vincent Osele]

When a task as a long description with some CRs, edit this task will triple the CRs.

Exemple:
Description entered first time:
[line1
line2]

When edited, description look like that:
[line1

line2

]

Nexty use :
- nl2br
- str_replace('\r\n',
- mysql_real_escape_string
- escapeQuery/unescapeQuery

Each OS have different ASCII chars for linebreak:
windows = \r\n
unix = \n
mac = \r

And nl2br doesn't work with \r\n in my system !
nl2br("blabla\r\nblabla") outputs "blabla<br />\r\n" !!

As nl2br is called 2 times sometime (when new task is created), \r\n are converted in two <br/> !

I suggest to define a new method in system called string2html (or whatever you want) that do
return str_replace(array("\r\n", "\n", "\r"), "<br />",$str)

And replace all nl2br with this function.

One can use a more complex method to integrated bbcode for example later...

I think there are 3 forms for text, some could be the same but there are différent:
1) text rendered on html page (with html tags)
2) text writen by users in a form
3) text inside database

Here an example for CR and image
1) text has <br/> or <p/>, and <img...> for example
2) text has \r\n or \n depends of system, and [img] in bbcode style
3) text could persist as \\n and [img] (same as 2 here)
or as <br/> and <img...> (like 1)

We must determine wich class or php do the conversions...
