Closes#33238, follow-up to
https://github.com/zed-industries/zed/pull/29625.
Changes:
- Removed `significant_indentation`, which was the way to introduce
indentation scoping in languages like Python. However, it turned out to
be unnecessarily complicated to define and maintain.
- Introduced `decrease_indent_patterns`, which takes a `pattern` keyword
to automatically outdent and `valid_after` keywords to treat as valid
code points to snap to. The outdent happens to the most recent
`valid_after` keyword that also has less or equal indentation than the
currently typed keyword.
Fixes:
1. In Python, typing `except`, `finally`, `else`, and so on now
automatically indents intelligently based on the context in which it
appears. For instance:
```py
try:
if a == 1:
try:
b = 2
^ # <-- typing "except:" here would indent it to inner try block
```
but,
```py
try:
if a == 1:
try:
b = 2
^ # <-- typing "except:" here would indent it to outer try block
```
2. Fixes comments not maintaining indent.
Release Notes:
- Improved auto outdent for Python while typing keywords like `except`,
`else`, `finally`, etc.
- Fixed the issue where comments in Python would not maintain their
indentation.
