example demonstrating the problem

* Problem:

- context: using XRangeBasedSmartTagRecognizer with 
           XTextMarkup.commitTextRangeMarkup (in java)

- XRangeBasedSmartTagRecognizer.recognizeTextRange 
  receives an XTextRange
- selecting a subrange from this XTextRange containing the part to be tagged
  and passing it to xTextMarkup.commitTextRangeMarkup
  results in wrong part of the text to tagged
  if a "Bibliography Entry" precedes it.

Files (in attachment.zip):

compile.sh : bash script to compile, pack into oxt
             and install the oxt into Libreoffice.
             Needs to be adjusted at the top (LO_PROGRAM_DIR, JAVAC, JAR, ZIP)

Makefile : mostly calls compile.sh (except for clean and distclean)

src/ : sources
      src/my/smarttags/Recognizer.java : recognizeTextRange() is the
                                         relevant part

sample.odt : Demonstrating the problem.

lo7 lo7-debug : shell scripts to run development Libreoffice.
             They need to be adjusted at the top (LO_PROGRAM_DIR)

Directories created by compile.sh:

tmp/ : used by compile.sh

out/ : generated files. The oxt file is at out/bin/mySmartTags.oxt

* Reproduce:

- (1a) Either build and install:

  - Assumes unix-like environment with javac, jar, zip, bash, egrep, sed,
                                       mkdir, rm, make
  - Edit the top of compile.sh: LO_PROGRAM_DIR, JAVAC, JAR, ZIP
  - make # It will also install the package using LO_PROGRAM_DIR/unopkg

- (1b): Or use prebuilt version:

  - unopkg add out/bin/mySmartTags.oxt

- (2) Open sample.odt in libreoffice with stdout/stderr visible on a console

  - Each "Hello" should be marked.
  - In row (1) they are
  - In row (3) the tags are mislocated.
  - On the console:
     - helloR() reports the length and content of the XTextRange received
     - marking() reports the content of the XTextRange passed to 
       commitTextRangeMarkup
