RE: Bug Report - Pull remote branch does not retrieve new tags

[Andrew Ducker <andrew_ducker@standardlife.com>]

Thanks Bryan, that does clear it up a bit.

The reason that this came up is that Visual Studio Code has switched from "git pull" to "git pull remote branch" when the "sync" button is clicked, and this has meant that tags are no longer being fetched.

What _does_ seem to work is adding "--tags" on the end of the git pull.  But this isn't actually in the documentation[1], and I'm a bit nervous that this is mid-deprecation.

Is "--tags" going away shortly?  Or are they ok to depend on this?

The bug is at https://github.com/Microsoft/vscode/issues/48211 if anyone wants to chime in with advice over there :-)

Thanks,

Andy
