Re: [PATCH] optionally disable overwriting of ignored files

Clemens Buchacher [off-list ref] writes:

By default, checkout and fast-forward merge will overwrite ignored
files. Make this behavior configurable.

Just mentionning an alternative, or complementary approach:

Instead of overwritting completely a .gitignore-d file, Git could
rename it, and warn the user kindly. For example:

$ git merge
...
Warning: existing ignored file 'foo' renamed to 'foo~'

(in case foo~ already exists, it's possible to use numbered backups
just like "mv --backup=existing" does for example)


That could complement your patch if core.overwriteignored is a
multiple-choice option instead of a Boolean:

- "overwrite" => current behavior
- "refuse" => your proposal
- "rename" => my proposal
