Subject: [PATCH 1/2] Add script to tweak output of 'alphapf' bibliography stile

"inlinelinks" in alphapf.bst caused PDFTeX to abort.
This was because href-ed long titles in Bibliography can cross
page boundaries. The combination of PDFTeX and "hyperref" package
can't handle such a situation.
You can avoid the issue by manually adjust page breaks. But in
perfbook, page boundaries in Bibliography can not be controlled
precisely.
This commit adds a script to convert \href related output of BiBTeX
on the fly. It shortens the href-ed part in title strings to the
beginning of two characters.
