16147,"MT Importer truncates double vertical spaces, munging paragraphs together",novasource,,"Movable Type 3.x-era exports don't use '''<p>''' tags. Like TinyMCE (and WordPress), a '''<p>''' in final rendered code is represented by two '''\n'''s in a row.

The importer strips out double '''\n'''s and replaces with a single '''\n'''. This causes paragraphs to lose their distinction upon import.

It does this because the '''$line''' variable was created by '''$line = $this->fgets($handle)''' (line 339). Then '''$line = trim($line)''' (line 340) strips out several characters, including '''\n'''.

Lines 455 and 456 add back the '''\n''' ''except'' on blank lines:
{{{
   if( !empty($line) )
   $line .= ""\n"";
}}}

So if a '''$line''' was nothing but a '''\n''', it's stripped by the '''trim''' function and becomes a 0 character line. Then the '''if( !empty($line) )''' declines to add back a '''\n'''.

Somehow this needs to be altered so that successive '''\n'''s aren't stripped. Otherwise paragraphs get vertically munged together.",defect (bug),reopened,normal,WordPress.org,Import,3.2.1,major,,,aren@…
