If files are so small that undolevels=1000 is sufficient, maybe you should
retype them instead?

There are additional options: for ext* filesystems you may use extundelete
application and for every filesystem you may open its device as a file and
search for parts of the text you still remember. Before doing the latter, ask
somebody for application that is able to do the job, Vim is not a good option
for this. I once did something similar with grep.

And I guess you now know why people use backups. Mercurial+bitbucket.org or
something similar for your code can also serve for this need.
