Thanks, but this would currently remove the ChangeLog
symlink[*] that I typically have in the top-level directory,
replacing it with a generated file. There is no need
to put such a file in the working directory.
[*] That ChangeLog symlink is generated per this excerpt from
vc-dwim --help:
EXAMPLE
Here's how to use vc-dwim in a project that does not version-control a
ChangeLog file. Create a repository just for your personal ChangeLog file
and make a symlink to it from the top-level directory of the project. For
projects that use git, I put this tiny auxiliary repository in a directory
named .git/c. You can use this bash/zsh alias to set it up and to create
the symlink:
git-changelog-symlink-init()
{
local d=.git/c
test -d .git || return 1
mkdir $d
touch $d/ChangeLog
(cd $d && git init && git add ChangeLog && git commit -m. -a)
ln --backup -s $d/ChangeLog .
}
