Subject: Fail lint CI if the PR doesn't target main (#3477)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/37542e64855ce21bd580f973ae5ce1ed86812a7a?hp=4e3303fa08e030722d6fd4d7fe7b8d44ef98991c

Fail lint CI if the PR doesn't target main (#3477)

Let's skip the check if we're running on a fork just in case someone
opens a PR against a branch on said fork as part of a PR review
upstream.
