Bug#560414: lintian: Don't warn about length of short description of text templates
Concerns check: too-long-short-description-in-templates
As can be seen on  there are a lot of warnings of this type, especially
for udebs. For udebs all cases are templates of type "text" that contain
text fragments that get dynamically included in other templates at
runtime. Because of that specific usage, the length of the short
description is not relevant.
To avoid these false positives, please add an exception for this warning:
- if the template type is "text" AND
- the package is a udeb
Reasons to request the exception are:
- udebs cannot contain lintian exceptions for binary packages (because we
don't want them installed in the D-I environment)
- we *do* want the warning for other template types than "text"
