This makes me remenber of copying weird behaviors of Delphi. As an 
example see the code:

  with AList do
    writeln('Set a string with space (aaaa;bb bb;cccc) to DelimitedText');
    DelimitedText:='aaaa;bb bb;cccc';
    writeln('Count: ',Count);
    writeln('Delimited text: ',DelimitedText);
    writeln('Strings: ');
    for i:= 0 to Count - 1 do
      writeln('  ',Strings[i]);

Set a string with space (aaaa;bb bb;cccc) to DelimitedText
Count: 4
Delimited text: aaaa;bb;bb;cccc

The space is used as a hardcoded delimiter being necessary to enclose 
with ". This limits the use of DelimitedText as a generic approach since 
is necessary to preprocess the strings being added though DelimitedText.

The argument to keep such behavior is compatibility but there will be 
always differences when porting code and the programmer must be aware. 
What is necessary is to document the differences. So in resume i think 
that fpc must not follow strictly Delphi, and in some situations, where 
appropriated, fpc can/must do things different/better than Delphi.
