Arseny Kapoulkine 00097df0d5 Improve C/C++ indentation flow for single statement blocks (#34549)
Before this, indentation did not automatically increase after
if/for/while/do/else statements in C++, and only increased after if/for
in C. This led to Zed using last line logic when inserting lines *after*
the indented statement, as well as not indenting the statement itself,
resulting in irregular indentation during typing.

Just adding indentation (similar to C) creates a new problem: now if a
scope is started with a brace on a new line, that brace is indented.
Thus we need to deindent it.

Using else_clause in the indent guide results in the else statement
being indented forward as well, so we need to deindent that too.

Note: the most significant issue for me is the one where indentation
jumps forward when inserting lines after indented lines. Unfortunately,
it appears that fixing that issue requires all of these other changes. I
would have preferred a simpler fix, but I'm not sure if disabling last
line behavior for C/C++ is appropriate as it probably breaks something
else, like cases where the file is incomplete and the statements can't
be parsed properly.

(note: the "else" snippet is completely breaking the flow here, but I
think that comes from clangd by default? Unfortunately I haven't found a
way to disable it cleanly but that is a separate problem that happens
right now too.)

Release Notes:

- Improve indentation during typing for C/C++ around if/for/while/do
blocks

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
