Since revision 11344 the preference parser (TWiki::Prefs::Parser.pm) adds useless spaces to the end of a value where it shouldn't because of this change:

-        } elsif( $type ) {
-            if( $line =~ /^(\s{3}|\t)+\s*[^\s*]/ &&
-                  $line !~ m/$TWiki::regex{bulletRegex}/o ) {
+        } elsif( defined $type ) {
+            if( /^(   |\t)+ */ && !/$TWiki::regex{bulletRegex}/o ) {

This code fragment analyzes the line after a preference setting and tries to decide if it is to be appended to the value or not like in

   * Set A_VAR = foo
   bar

sets A_VAR to

foo
   bar

The problem with the new regex /^(   |\t)+ */ is that it matches a continued value only consisting of spaces. So

   * Set B_VAR =
<space><space><space>
does not set B_VAR to the empty string but to

\n
<space><space><space>

... which is a bad way to be "white-space-sensitive".

The fix would be to check (as the original regex did) that there is at least one non-white-space following:

--- lib/TWiki/Prefs/Parser.pm   (revision 11375)

         } elsif( defined $type ) {
-            if( /^(   |\t)+ */ && !/$TWiki::regex{bulletRegex}/o ) {

                 $value .= "\n".$_;
             } else {

CDot, as you've done the last checkin in that area, do you agree?
