Not a bug report, but this is from the emacs-devel thread
"Tree-sitter: Transcendental things".
Improve tree-sitter thing navigation functions to handle the

Variable names to control indentation have never been
standardized, but over the years some conventions have naturally
arisen, mostly the use of `FOO-indent-offset`,
`FOO-basic-offset`, or `FOO-indent-level` for `FOO-mode`.
When the new TS modes were introduced, a mistake was made that
I failed to catch at the time, where those modes used
`FOO-mode-indent-offset` instead of the "standard" `FOO-indent-offset`.
In order to save packages like `editorconfig-mode` and `indent-bars-mode`
from having to cater to yet-another-convention, rename those
vars to what they should have been all along.

The greedy regexp matching, broken scoring and broken highlight were
sources of frequent complaints about the 'flex' matching style. This
commit fixes that.
Inspired by the 'hotfuzz' style (available at
https://github.com/axelf4/hotfuzz) it uses a modified version of Gotoh's
1982 dynamic programming algorithm. It is strictly more correct than the
"old" flex. For example, when matching the pattern 'goto' to no longer
will 'eglot-format' be sorted before some hypothetical much better
'goobarbaz-goto'. And of course the highlighting is also correctly
placed on the 'goto', not scattered across the candidate.
Regarding performance, it is faster than the naive 'flex', primarily
because of the Elisp rewrite in minibuffer.el. The matching and costing
algorithm matters but is not the bottleneck.
The Elisp parts of the style were almost completely decoupled from the
pcm/substring styles in lisp/minibuffer.el. Only
'completion-flex-try-completion' uses some of pcm's code for pattern
augmentation.
