Hello Felix,
The biggest problem is that after changing around, I thought it all works well and did not do any backups of how my style-file worked before until realising the mess. 1498 and upwards if !=* is not working 100% correct, is simply unusable. This was a real degradation. Now I will need to spend hours trying to get a working style-file for 1497 again if soon >1500 is not getting correct behaviour again.
I can't believe you don't have your style files under version control. It's so easy with any of the "modern" SCM programs (e.g. bazaar, hg, git) - you don't have to make a separate repo like you do with old-fashioned SCM systems (cvs, svn). Just go to the directory/folder that contains the files you want to put under version control and say: hg/bazaar/git init Then you can start committing changes. It's a no-brainer. Mark
