[Gnu-arch-users] "Sparse" trees - exclude RE?

[Ulrich Pfeifer]

Hello,

I am wondering what the recommended method for maintaining "sparse
trees" would be.  Often it is convenient to maintain a small part of a
bigger tree in a project.  That could be a part of the Linux tree.
Currently I have a tree containing documents and some small tools to
manipulate them.  The documents are maintained by other means, but the
tools should go in an arch repository.  I could certainly separate the
stuff into two directories 'doc' and 'bin' and maintain only the
second with arch.  That might not be convenient in any case though.

My solution was to use the following line in =tagging-method:

   precious 
^(\+.*|\.gdbinit|\.#ckpts-lock|=build\.*|=install\.*|CVS|CVS\.adm|RCS|RCSLOG|SCCS|TAGS|.*(\.pdf|\.gif|\.htm|\.jpg|\.ppt|\.xls|\.doc))$

That did work, but I would have expected this to be the preferred
method:

   exclude ^(.arch-ids|\{arch\}|.*(\.pdf|\.gif|\.htm|\.jpg|\.ppt|\.xls|\.doc))$

Setting the exclude RE does not have an effect when 'tagline' is used
as tagging method with tla 1.0 and 1.1.  I expected that it would shut
up tree-lint.  Is it a bug - or why was it designed that way?
