RFR: 8375649: idea.sh script adds source paths in a single, enormous, line to jdk.iml.

[David Beaumont]

Allow replacement string to contain embedded newlines to split entries.
This turns output like:


    <content url="file:///home/david/dev/test/jdk">
      <sourceFolder url="file:///home/david/dev/test/jdk/open/src/java.base/linux/classes" isTestSource="false" /> <sourceFolder url="file:///home/david/dev/test/jdk/open/src/java.base/unix/classes" isTestSource="false" /> <sourceFolder url="file:///home/david/dev/test/jdk/closed/src/java.base/share/classes" isTestSource="false" /> ... another 10k chars on the end of this line ...


into:

    <content url="file:///home/david/dev/test/jdk">
      <sourceFolder url="file:///home/david/dev/test/jdk/open/src/java.base/linux/classes" isTestSource="false" />
      <sourceFolder url="file:///home/david/dev/test/jdk/open/src/java.base/unix/classes" isTestSource="false" />
      <sourceFolder url="file:///home/david/dev/test/jdk/closed/src/java.base/share/classes" isTestSource="false" />
      ... one entry per line ...
