Subject: [PATCH] new release script

inspired by
https://blog.danslimmon.com/2019/07/15/do-nothing-scripting-the-key-to-gradual-automation/
and https://drewdevault.com/2019/10/12/how-to-fuck-up-releases.html

care has been taken to make it posix compliant. however, it does by
default depend on my fairly unusual setup to be present, which can
however be easily overridden (see script for details).

+(helps to) prepare a new VimFx release. 
+
+note: by default, my (@girst's) pretty idiosyncratic development environment is
+assumed to be present (i'm pushing unstable commits to a second git-remote and
+only push 'release-quality' commits to upstream). these are easily overwritten
+by passing them in the calling environment. alternatively, changes to can be
+temporarily ignored by git with `git update-index --assume-unchanged FILE`.
