patch
Hi,
For some reason I have some Word documents that have a header/footer that
causes the following StringIndexOutOfBoundsException:
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String
index out of range: -1
at java.lang.String.substring(String.java:1937)

org.apache.poi.hwpf.usermodel.HeaderStories.getAt(HeaderStories.java:162)

After investigation it turns out that prop.getEnd() was smaller then
prop.getStart() in one case and in the other case both prop.getStart() and
prop.getEnd() were bigger then headerStories.text().length. Therefore I
implemented two additional checks in the HeaderStories.java in the getAt
method, see attached patch. Could this be added to the next release if
approved?
Thanks in advance,
Sjoerd
