ucf to manage /etc/{,v,gv}imrc

[Pierre Habouzit]

we had some ... problems regarding /etc/vimrc upgrade, and I was asking 
myself if the solution couldn't be to use ucf.

for those who don't know it, it has a nice --three-way option that allow 
the "merge" of the maintainer and user modifications, which very often 
« just works »


this would need to put our default configuration files .e.g. 
in /usr/share/vim/conffiles/{,v,gv}imrc and :
 * in vim-(gui-)?common.install : change the runtime/vimrc install to be
   in conffiles instead
 * in vim-(gui-)?common.postinst : add 
     ucf --three-way /usr/share/vim/conffile/$FILE /etc/vim/$FILE
 * add vim-(gui-)?common.postrm, and in case of purge do :
     ucf --purge /etc/vim/$FILE
     rm -f $FILE

and that's all.

that would kept us out of trouble due to the merge problems we 
encountered with /etc/vimrc, in an elegant way.

Moreover, I tested such a thing on my machine, and downgrading of 
packages still work.


what do you think ?
