 I am using `esc_atr(ltrim(rtrim(br2nl($meta_value))))` to place the value
 of post meta in textarea metabox I have created in my custom post type.

 {{{#!php
 <textarea id="<?php echo $id_name; ?>"
    name="<?php echo $id_name; ?>"
    rows="7" cols="80"
    style="width:100%" maxlength="<?php echo $maxlength; ?>"
    placeholder="<?php echo $placeholder_text; ?>"
    <?php if($is_required){ ?>required<?php } ?>>
    <?php echo esc_attr(ltrim( rtrim( br2nl($input_value)) ) ); ?>
 </textarea>
 }}}


 But whenever I go to edit the post, inside all textarea metaboxes values
 are pre-loaded with leading spaces (exactly 10 spaces) and additional line
 breaks!

 Also tried `esc_atr(trim(br2nl($meta_value)))` with no avail.
