Bug#809577: lintian: More accurate description for tag postinst-has-useless-call-to-ldconfig

[Rafael Laboissiere <rafael@laboissiere.net>]

Package: lintian
Version: 2.5.39.1
Severity: normal

In the description of tag postinst-has-useless-call-to-ldconfig it is 
stated that "[t]he postinst script calls ldconfig […]".  I ran into a 
case where ldconfig is actually called in the triggers script and the 
above tag is issued.  It took me a while to figure out where the 
problem came from.

Could you please update the description of the tag, stating something 
like this:

   The postinst or the triggers script calls ldconfig even though no
   shared libraries are installed in a directory controlled by the
   dynamic library loader.

By the way, it would be also good to change the tag itself to 
something like "postinst-or-triggers-has-useless-call-to-ldconfig".

Thanks,

Rafael Laboissière
