Josh Stone 29c3421391 Don't return any TextEdit if formatting is unchanged ... I found that `textDocument/formatting` was always returning a full `TextEdit` replacement, even when there are no changes, which caused Vim (w/ vim-lsp) to always indicate a modified buffer after formatting. We can easily compare whether there were changes and return `null` if not, so the client knows there's nothing to do.		2020-09-16 10:05:41 -07:00
