--text follows this line-- This is more of a feature request/request for information. This concerns emacs on windows 10. I work in a small team that has been using Dreamweaver to maintain a website maintained on a local network webserver. We each maintain a local copy of the website and perform checkouts on the remote files. After editing is complete we push the changes and check the files in. Dreamweaver uses lock files to control the checkin/checkout processs. I've recently started using emacs and have found that emacs also uses lock files, but the format is different from the format used by Dreamweaver. I can change `create-lcokfiles` to nil to disable the creation of lockfles, but I cannot modify the format or naming convention used. A dreamweaver lock file for test.html would be test.html.LCK and the contents would contain the name and email address of the user who created it (like so: WesEllis||wes@gnu.org). Is there a way, or could we create a way to customize lockfile format and naming conventions?
