XML ConstructingParser too aggressive trimming whitespace around character references

[scabug]

when preserveWS = false. example:

Welcome to Scala version 2.8.0.RC3 (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_20).

scala> xml.parsing.ConstructingParser.fromSource(io.Source.fromString("<x>a &amp; b</x>"), preserveWS = false).document.text
res0: String = a&b

note that spaces on either side of the escaped ampersand have been lost.

I can't see why you would ever want this behavior. and I'm not an XML laywer, but section 4.4 of the XML 1.0 spec suggests that the character encoded by a character reference should be "retrieved and processed, in place of the reference itself, as though it were part of the document at the location the reference was recognized"

perhaps vaguely related: #3062

the "&SI-38;" in the description seems to be an artifact of the Trac-to-JIRA transition. It should read:

scala> xml.parsing.ConstructingParser.fromSource(io.Source.fromString("<x>a &amp; b</x>"), preserveWS = false).document.text
res1: String = a&b

The scala-xml library is now community-maintained. Issues with it are now tracked at https://github.com/scala/scala-xml/issues instead of here in the Scala JIRA.

Interested community members: if you consider this issue significant, feel free to open a new issue for it on GitHub, with links in both directions.
