XML pretty-printing introduces weird whitespace.

I'm running version HTML Tidy for Linux version 5.6.0 and I've got some weird white-space pretty printing issue.
Given a small XML file like this -

<Small>
    <LongLongElement some:attr="aaaaaa"
            other:attr="bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb"
            >
        <InnerElement/>
    </LongLongElement>
</Small>

and invoking tidy as follows

tidy -xml \
    -i  \
    --quiet yes \
    --indent-attributes yes \
    --indent-spaces 4 \
    --literal-attributes yes

the output produced has some weird trailing white space.

<Small>
    <LongLongElement some:attr="aaaaaa"
                     other:attr="bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb">
                      <- This is actually whitespace
        <InnerElement />
    </LongLongElement>
</Small>

Is this the expected behavior? If so, is there any flag I can use to not have that whitespace be added?
I presume the element name length matters but attribute value length doesn't because of --literal-attributes.

@pinkisemils, sorry, this not so pretty, pretty print bug still persists today, in next ... 5.7.28++

Added your sample to my test collection - geoffmcl/tidy-test@6370f99 - in_864.html, and added a -config cfg_864.txt, for consistent testing...

I think it is the --indent-attributes yes option, that is involved in this... it outputs a whitespace indent... but...

The xml pretty printer, has NOT had a lot of attention... ever... hopefully a relatively easy fix... never output a new line character, if all you have is white space... or something like that...

Look forward to feedback, patches, or PR, etc... thanks...
