The question formerly titled "Does Stirling's formula give the correct number of digits of n!?" is now titled "Does Stirling's formula give the correct number of digits of n?". This was not due to an edit, and is incorrect. I speculated that this might be the result of a retroactive automatic systemwide editing of punctuation.
Searching meta.SO, I found this answer that seems to show that this was done intentionally. I can understand the motivation to clean up questions with bad punctuation, but I am concerned that it may remove certain instances of correct notation appearing in titles. There are plenty of ways to work around it in the example given above (e.g. by writing
...n factorial? or
...$n!$?). But I wonder if it is worthwhile enough that we should have to work around it, and I wonder if there have been/will be other instances of valid mathematical notation conflicting with automatic punctuation editing that is not as easy to work around, or other cases of old posts like the one above that may confuse readers during the potentially long interval before they are corrected.
I am not making this a feature request, because I would like to hear what others think. I am undecided on whether the benefits outweigh the costs. Admittedly, I may have (luckily) happened upon the only instance of the changes making a title incorrect, but I have no way of knowing. Please share your thoughts if you would like to.
