As a avid windows+JtR user, I like the proposed changes. Windows
doesn't have a text reader/editor for the CMD line. Most of windows is
GUI, powershell is changing that, but I've never seen anyone "vi" in
powershell. The file extenstions are a great idea. The Unix2Dos
conversion/line endings are necessary if the OS defaults to Notepad
(it still does, and alternate endings still aren't properly
understood) by that one program. Wordpad, MS Word, Notepad++ etc...
those have no issues with D or U line endings. But for some dumb
reason, Notepad still can't handle it.
I would have done these vary changes to my own contributed builds, but
I thought they may have been frowned on by *nix users. I've seen
something similar happen to Snort, which offers windows builds, but
uses the /etc/this/n/that directory structure rather than
c:\snort\something\something file structure in the Snort.conf. If the
configure script or make process would launch something to change
these file extenstions to .txt (which removes any ambiguity, from any
OS what is contained within) I'm all for it.

Again I've used wrappers for some python scripts in my contributed
builds because most of the 2john scripts are very useful and it's hard
for most casual users to know how to download needed python/ruby/perl
packages just to extract the hash they need from a 7zip file. The line
endings for scripts I don't feel need changed to CRLF.

.conf doesn't default to anything in windows, you're asked to choose
an editor/viewer, if you chose Notepad it would not render properly.
Just about any other editor will know better however.
