commit 636d36e37a0d2b6adb2e12d802ff4794ccbba336
Author: Alan Donovan <adono...@google.com>
Commit: Dominik Honnef <domi...@honnef.co>
Add go-{browse-{freesymbols,doc,assembly},rename}
These four helper functions provide convenient ways to access
gopls server functionality without the user needing to worry
about how their LSP client does things. They should work for
eglot and lsp-mode (though I haven't tested the latter).
