           Summary: DDOC removes leading space in D_CODE macro
           Product: D
           Version: 2.011
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: ddparnell bigpond.com


The following text ...
$(D_CODE
  aaa
  bbb
  ccc
)

generates ...

<pre> aaa
  bbb
  ccc
 </pre>

Notice:
(A) That the two spaces before "aaa" have been rendered with only one space.
(B) One space preceeds the </pre>. 

Because the definition of D_CODE is <pre>$0</pre> I expected this instead to be
generated ...

<pre>
  aaa
  bbb
  ccc
</pre>

From the Ddoc spec: "Macros can have arguments. Any text from the end of the
identifier to the closing ')' is the $0 argument".

The spec does not elaborate on where is the end of the identifier and the start
of the text. According to the spec, an undefined number of whitespace
characters may be skipped to get to the start of the argument, the rest of
whitespace may be arbitrarily replaced with <br><br>. :)

The start of the argument might have been defined as the first non-whitespace
character or the first vertical space character, whichever comes first.

I wish it was using the rule "The start of the argument might have been defined
as the first non-whitespace character or the first vertical space character,
whichever comes first." because then it would come out as I had expected. But
it is definitely just eating the first space character and leaving the rest.
Also, in my original post, point (B) is not true. I messed up the test file.
Only point (A) is still at fault, IMHO.

Ping. Isn't this bug trivial to fix? And it is an error-prone one, because us
usually expects that the start of the argument is "the first non-whitespace
character", but it isn't now. Worst of all it is undocumented now. `WEB` macros
suffers from this bug, look at broken links to STL at
