Escape sequence to show {alias} in text is FUBAR about fractive HOT 3 CLOSED

I did some snooping around in the SkipEscapedSubstring function and couldn't find anything that looked wrong about it. It's really weird.

Is the same \{alias} you're escaping also in use elsewhere in the same .md file in a non-escaped fashion, e.g. {alias}? Because when that's the case, I can repro this as such:

Display this as-is: \{myAlias}
But replace this one: {myAlias}

You'd expect the result to be:

Display this as-is: {myAlias}
But replace this one: foo

But what actually happens is:

Display this as-is: \foo
But replace this one: foo

The reason for that is near the end of Compiler.ReplaceAliases when we identify a non-escaped alias for replacement, we then proceed to replace all instances of that alias in the entire .md file, without checking each subsequent one for an escape. The solution to that is to replace only the alias instance we're looking at right now, instead of doing a global replace. That applies to both the regular and regex forms of replacement.

If I escape an alias that's not expanded elsewhere, it works fine, e.g.

Display this as-is: \{unusedAlias}
But replace this one: {myAlias}

...correctly displays as:

Display this as-is: {unusedAlias}
But replace this one: foo

Let me know if you're seeing a different repro for this, or a different issue altogether.

Off the top of my head, that is probably the use-case, yeah. Because I was trying to make an example that would show macro syntax and subsequently show the macro output, if I remember correctly.
