I typed the line below and it shows me the correct diff:
svn diff file:///data/svn/webprojects/mediawiki/branches/1.5.3-osu file:///data/svn/webprojects/mediawiki/tags/mw-1.6.1 | less
when I typed:
svn merge file:///data/svn/webprojects/mediawiki/branches/1.5.3-osu file:///data/svn/webprojects/mediawiki/tags/mw-1.6.1
it sarted showing:
D maintenance/archives/.htaccess
and a whole bunch of other files deleted
I want to merge the difference between this tag and this branch into my local working directroy
