Mike McQuaid	2b9edf72bc	unlink: unlink only keg-only versioned formulae. ... As otherwise we unlink those that don't conflict e.g. `gcc@8` and `gcc@9`.	2020-11-16 14:45:15 +00:00

Mike McQuaid	849034c368	Improve @-versioned formulae linking. ... The way we currently handle @-versioned formulae linking is pretty labourius: - it requires extensive use of `link_overwrite` to avoid the `link` stage failing on certain install/upgrade scenarios - we teach people to use `brew link --force` whenever they wish to link a versioned formulae when it's pretty obvious what's expected in that situation Instead, let's: - automatically unlink other versioned formulae when linking a versioned formula (either through `brew link` or `install`/`upgrade` /`reinstall`) - notify the user what we've done (with the same messaging as if they had run `brew link` manually)	2020-10-29 13:35:03 +00:00
