[gmx-developers] File name "*s" trouble with cygwin/git/windows

[Erik Lindahl]

Hi Chris/Mark,

Of course they shouldn't be there :-)

We seen a couple of mistakes like this before; the issue is that we  
converted the entire cvs repository to git using the standard  
translation scripts (to keep our history), but apparently there are  
some bugs in that script that cause some files removed years ago to  
resurface.

I don't seem to be able to do git push over my 3G cellular broadband,  
but if nobody else fixes it by tomorrow I'll have a go at it through  
an ssh connection!

Cheers,

Erik
