Right.
> So it's not a noop,
It's a no-op in the sense that it does nothing. Of course, it is still the case
that, as the doc string says, the \= itself "is discarded". What remains is the
\ that was escaped.
Not sure what your confusion is. \= escapes the char that follows it. What
does escaping mean in this context? Preventing \ from having any special
behavior when it precedes =, [, etc.
The point is that it is not the pair of characters \=, \[, etc. that is escaped.
\ is the only char escaped: it is prevented from doing anything special; it just
appears in the output as is. Because \ gets escaped, it has no special
`substitute-command-keys' effect on what follows it, whatever that might be.
> and the fix I applied was correct.
Dunno what it was.
What I described is a proper fix, IMO.
