* Rewrite the real file if history file is a symlink When the history file is a symbolic link, `fish` used to overwrite the link with a real file whenever it saved history. This makes it follow the symlink and overwrite the real file instead. The same issue was fixed for the `fish_variables` file in622f2868efrom https://github.com/fish-shell/fish-shell/pull/7728. This makes `fish_history` behave in the same way. The implementation is nearly identical. Since the tests for the two issues are so similar, I combined them together and slightly expanded the older test. This also addresses https://github.com/fish-shell/fish-shell/issues/7553. * Add user-facing error when history renaming fails Currently, when history file renaming fails, no message is shown to the user. This happens, for instance, if the history file is a symlink pointing to another filesystem. This copies code (with a bit of variation, after reviewer comments) from589eb34571/src/env_universal_common.cpp (L486-L491)into `history.cpp`, so that a message is shown to the user. * fixup!
