 Priority:  normal          |   Milestone:  2.2.3             
Component:  Administration  |     Version:  2.2.2             
 Severity:  normal          |    Keywords:  update_option trim
----------------------------+-----------------------------------------------
 When using wordpress option function "update_option" and the value of the
 option is a string containing trailing spaces (wether in front or at the
 end), these spaces will be removed. This can destroy the option value
 since spaces are chars like any other chars in a string. The option value
 then is saved crippeled into the option system and each time the value is
 requested again trailing spaces are missing.

 The defect is inside the update_option() function on line 281 in
 functions.php. In line 289 the option value type is checked to be a string
 and if it is a string, the string value will be trimmed:


 {{{
 if ( is_string($newvalue) )
                 $newvalue = trim($newvalue);
 }}}

 It is totally unclear why this happens, the sourcecode isn't documented in
 any way. I applied a diff against the current SVN that removes these two
 lines of faulty code.
