Description of problem:

I have an RPM %description that contains this text:

%description
[..]
In order to get access to the hive files themselves, you can copy them
from a Windows machine.  They are usually found in
%%systemroot%%\system32\config.  For virtual machines we recommend
[..]

RPM itself correctly converts the double percent signs to single percent
signs, ie:

$ rpm -qip /home/rjones/rpmbuild/SRPMS/hivex-1.1.2-1.fc12.src.rpm
[..]
In order to get access to the hive files themselves, you can copy them
from a Windows machine.  They are usually found in
%systemroot%\system32\config.  For virtual machines we recommend

However rpmlint gives a warning:

hivex.src: W: macro-in-%description %systemroot

I think this warning is wrong.

Version-Release number of selected component (if applicable):

rpmlint-0.91-1.fc12.noarch

rpmlint-0.94-1.fc13.noarch gives a slightly different warning:

hivex.src: W: unexpanded-macro %description -l C %systemroot

How reproducible:

Always.

Steps to Reproduce:
1. Use %%systemroot%% in a description.
2. Build the RPM.
3. Compare RPM output to rpmlint output.

Additional info:

I cannot find any documentation on the correct use of escaping
in RPM spec files...
