Bugs in sub argsfromdir of git-cvsserver

["Le" <le_wen@xxxxxxxxxxxxxx>]

Hi, all,

I found a bug in git-cvsserver.
sub argsfromdir
{

   if ( scalar(@{$state->{args}}) == 1 )
   {
       my $arg = $state->{args}[0];
       #$arg .= $state->{prependdir} if ( defined ( 
$state->{prependdir} ) );
       $arg = $state->{prependdir} . $arg if ( defined ( 
$state->{prependdir} ) );
       $log->info("Only one arg specified, checking for directory 
expansion on '$arg'");
...
   }
...
}

It makes not sense of the above remarked out code.

But when I use the code followed remarked out, I have problem to use cvs 
diff or cvs log in a sub directory of the root (may other commands as 
well). Eg.:

I have a project called test1 and in test1 there is a test2 subdirectory 
and a file test2/test3.txt.
I have no problem to cvs diff and cvs log in test1 directory. But if I 
enter test1/test2 to check these commands then they are not working.

I tried to fixed the problem to remarked out the code:
#$filename = filecleanup($filename);
in req_log and req_diff, then both cvs diff and cvs log work.

In
sub filecleanup
{
...
$filename = $state->{prependdir} . $filename;
return $filename;
}

inserts $state->{prependdir} into the $filename.

But I don't know if what I did brings incompatibilities.

Can anybody check this issue?

Thanks!
