bug#49510: [PATCH] gnu: Add PuTTY.

[terramorpha]

Hi, thank you for the review.

I corrected the version of the package (putty doesn't use 
major.minor.patch, only major.minor),
I fixed the lines that were over the 80 character limit, re added the 
check phase, corrected the
formatting and put in the expat license. However, I do not know what you 
mean by the "ChangeLog
part of the commit message", I thought that standalone patch didn't have 
a commit message attached.
Could you elaborate?

Here is the modified patch.
