Abandoned change to not modify files where fmt makes no changes

[hellified]

There was an issue: #128
And a code change: 3d478b3

But it looks as though the change was abandoned?
I was hoping either to have the change merged in, since I'm having the same issue as the original issue filer, or learn what the alternative/workaround was.

Yeah, I don't know why...

Looks like the design of that section shifted a lot:

templ/cmd/templ/fmtcmd/main.go

Lines 122 to 136 in 8d27ad1

	func format(write writer, read reader) (err error) {
	fileName, src, err := read()
	if err != nil {
	return err
	}
	t, err := parser.ParseString(src)
	if err != nil {
	return err
	}
	w := new(bytes.Buffer)
	if err = t.Write(w); err != nil {
	return fmt.Errorf("formatting error: %w", err)
	}
	return write(fileName, w.String())
	}

It would need a revisit to make that work, but seems like a reasonable use case to support.

Ah, that's wonderful. Just fell through the cracks I guess. Back on track now, so no worries. I'll just watch the PR and anticipate the release.
Thanks!
