As I have observed in two recent questions, there's been some recent change to the syntax for inline code in comments. Let me here document the changes I found out so far (as in found out the hard way):
A backtick must now always be escaped. Until recently,
\catcode`A=\active; one didn't have to escape backticks before letters.
updated Update: Related to the 2nd part of #1: Now you can have a letter immediately after the closing backtick, so that you can have e.g. "
<br>s" in a comment. But this only works if you also have
<br>in the comment.
There's no backslash escaping for
You mustn't have spaces in the beginning of the inline code.
While I'm perfectly happy with these changes per se, I have two problems:
They affect the old comments as well, making them distorted in some cases. (Jeff has corrected this on (meta.)tex.sx, except for the 2nd part of #1 above; thanks a lot!)
Those changes happened without any notice or explanation.
Thus my feature-request: Can we please have some place where one can look up all changes of this sort? And in the future, as there are more changes to come, wouldn't it make sense to leave the rendering of old comment untouched?
(I have no way of knowing if my list above is complete, so I'd really like to know what exactly the recent changes were. Sorry that I keep bumping this post, but I'm still discovering new kind of behaviour unknown to me before. Which may underpin the point I'm making.)
