"git-commit" language ignores indent setting in languages.toml

[m4rch3n1ng]

my languages.toml looks like this:

[[language]]
name = "git-commit"
indent = { tab-width = 4, unit = "\t" }

but when i want to edit a git commit message (via e.g. git -c core.editor=helix commit --amend) it still uses 1 space indentation (pressing tab inserts one space, and :indent-style returns "1 space")

it is very possible that i a doing something wrong, but currently the only way i have found to fix that is by manually setting :indent-style t 4 every time i want to edit a git commit message.

Unable to reproduce (tab works with OP languages.toml).

i think i found the underlying issue: i use git commit --verbose (with that i still can't get it to reproduce on the helix repository, i think because it uses spaces), but i can consistently reproduce it both with a build from master and the current release:

$ git clone https://github.com/m4rch3n1ng/mayland # or any other rust repository that uses tabs
$ cd mayland
$ git -c core.editor=helix commit --amend --verbose

With --verbose I can reproduce the error with that mayland repo.

We auto-detect the indentation of a file and this sometimes produces bad interpretations, also see #9556

Aside from short files we should probably also try to ignore comments in the calculation, and treat the part after the scissors in the commit message as a sort of block comment

I had a go in #12810. It effectively skews the indent heuristic to only prefer guessing if the amount of indent of a type exceeds the amount of lines with no indents at all.
