I do admit it is a bit confusing.. But I couldn't think of a better name,
or better way to do this. And no I can't use path.glob* as a direct
replacement. For example (1)..

####
ECHO >>> [ path.glob ../src/AntTweakBar : *.c *.cpp : *Direct3D*.* ] ;
ECHO <<< [ glob-ex ../src/AntTweakBar : *.c *.cpp : *Direct3D*.* ] ;
local qqq-project = [ project.current ] ;
local qqq-source-location = [ path.root [ $(qqq-project).get
source-location ] [ path.pwd ] ] ;
local qqq-search-paths = [ sequence.transform project.glob-path-root
$(qqq-source-location) : ../src/AntTweakBar ] ;
ECHO === [ sequence.transform path.relative-to $(qqq-source-location) : [
path.glob $(qqq-search-paths) : *.c *.cpp : *Direct3D*.* ] ] ;
####

Results in:

####
>>>
<<< ../src/AntTweakBar/LoadOGL.cpp ../src/AntTweakBar/LoadOGLCore.cpp
../src/AntTweakBar/TwBar.cpp ../src/AntTweakBar/TwColors.cpp
../src/AntTweakBar/TwFonts.cpp ../src/AntTweakBar/TwMgr.cpp
../src/AntTweakBar/TwOpenGL.cpp ../src/AntTweakBar/TwOpenGLCore.cpp
../src/AntTweakBar/TwPrecomp.cpp
=== ../src/AntTweakBar/LoadOGL.cpp ../src/AntTweakBar/LoadOGLCore.cpp
../src/AntTweakBar/TwBar.cpp ../src/AntTweakBar/TwColors.cpp
../src/AntTweakBar/TwFonts.cpp ../src/AntTweakBar/TwMgr.cpp
../src/AntTweakBar/TwOpenGL.cpp ../src/AntTweakBar/TwOpenGLCore.cpp
../src/AntTweakBar/TwPrecomp.cpp
####

So I either replicated the code from glob-*ex in my project or use put it
in BB in some form.

(1) And for those that don't see it, the key difference is that the project
glob rules take into account project relative source paths, while path.glob
doesn't.
