Review Comment:
> try to avoid reusing variables as it's bug prone

yup please look at the context of the code (the full code) yes it's not idea
but it;s how the rest of the code is and I don't want to change everything this
could be part of another PR if you like.
> Also, this is combining lines with no space in between one line and the
next. Is that what you want?
> Ability to split grouped packages over multiple lines

> Project: Maven Javadoc Plugin
> Issue Type: New Feature
> Components: javadoc
> Affects Versions: 3.10.0
> Reporter: Richard Eckart de Castilho
> Assignee: Olivier Lamy
> Priority: Major
>
> When configuring groups, the packages in the group need to be written on a
> single line separated with colons.
> {noformat}
> <groups>
> <group>
> <title>Core</title>
> <packages>
> org.apache.uima.analysis_component:org.apache.uima.analysis_engine
> </packages>
> </group>
> </groups>
> {noformat}
> If there are many packages that can not easily be captured using a prefix
> pattern, this yields a very long line.
> It would be greate if one could split the packages over multiple lines such as
> {noformat}
> <groups>
> <group>
> <title>Core</title>
> <packages>
> org.apache.uima.analysis_component:
> org.apache.uima.analysis_engine

> </group>
> </groups>
> {noformat}
> The code internally already calls
> {{org.apache.maven.plugins.javadoc.JavadocUtil.quotedArgument(String)}} to
> sanitze the line breaks away, but it seems the whitespace still breaks it and
> javadoc tool in the end only recognizes the first package in the multi-line
> group.
> Even nicer may be.
