| ``<tab>`` at the beginning of the line in :mod:`pdb` multi-line input will fill in a 4-space indentation now, instead of inserting a ``\t`` character. | |||

There was a problem hiding this comment.
I'd add this to what's new in 3.14.

We supported multi-line input in pdb in 3.13, but the tab indentation does not work in its best shape. It inserts a
\tcharacter, which means the first<tab>will introduce a 2-space (at least looks like it) indentation, and the next ones will introduce a 8-space one.This PR made it a bit smarter. Now a
<tab>at the beginning of the line (before any non-space text) will auto-fill a 4-space indentation. For example,\tand\twill both create a 4-space indentation.This is not the smartest feature, it's not as good as pyrepl where the indentation is inserted when a new line is created. However, I think it's much better than what we have now.
The ultimate goal is to use pyrepl for pdb, so I don't think duplication too much code to make pdb work slightly better now is that rewarding.
