git-mergetool changes file rights?

Hello,

I've stumbled upon very weird problem:
grek@linux-p3yg:~/asf/git/infrastructure/apache-git-mirrors/bin> git --version

Notice rights for email-update.sh.

What's going on here?

Looking at this sequence of error messages it looks like mergetool ran
kdiff3 and this 'succeeded', but when mergetool came to 'git add' the
result of the merge it fell over in a heap because it couldn't read
the file because of the strange ---x------ permissions.

mergetool just uses mv to create a backup of the to-be-merged path and
then uses cp to recreate the original path before invoking kdiff3. I
haven't managed to get cp to do anything other that use the same mode
as the source file for a copied file.

What version of kdiff3 are you using? I ask because this fix looks
like it may be relevant:

http://kdiff3.svn.sourceforge.net/viewvc/kdiff3/trunk/kdiff3/src-QT4/fileaccess.cpp?r1=84&r2=96

The changelog for 0.9.95 includes this:

- Fixed permissions when writing executable file. (Un*x only)

Hi Charles,

I didn't thought of blaming kdiff3 which seems to be the real guilty for my problems. I'm using 0.9.94 version but I'm
in the process of update.

I'll try that version and report back if it fixes my problem.

Thanks for your help!
