[O] Link abbreviations: include abbreviation table and linkwords with spaces

[ST]

Hello,

after reading "4.6 Link abbreviations" of the manual I have two
questions:

1. is it possible to define linkwords with spaces, like this: [[Harry
Potter:Chapter1]], it looks much more nice than
[[Harry_Potter:Chapter1]]?

2. is it possible to define a "links catalog" of abbreviations, like

#+LINK: bugzilla  http://10.1.2.9/bugzilla/show_bug.cgi?id=
#+LINK: google    http://www.google.com/search?q=%s

and then include them in all possible org files with

#+INCLUDE: "links_catalog.org"

Will the links be clickable?

Thank you!
