Howto get repository up2date after pull with touching as less as possible files in the working directory

Howto get repository up2date after pull with touching as less as possible files in the working directory

[Thomas Glanzmann]

Hello alltogether,
at the moment I ensrure that there are no dirty files before the pull
and do a

	git-read-tree HEAD
	git-checkout -a -f
	git-update-cache --refresh

this is suboptimal because all the files in my working directory get a
new timestamp and if I call make everything is recompiled (ccache helps,
but is not the solution to this problem).

So what is the right way to touch *only* the files which are dirty. Are
there any shortcuts? Or should I call 'git dirty' pipe that to
git-checkout -f?

	Thomas

Do git-read-tree -m HEAD instead. That will keep the original stat
information and checkout will rewrite only files it needs to.
