Hi, Sergey!
Thanks for the decent work!
I've checked, at a rough guess, that there are no line numbers to be
updated in these changed files.
LGTM, with an ignorable suggestion below.

The patch sets a max length with 80 symbols for lines with code
and max length with 66 symbols for lines with comments in luacheck
configuration file [1] and fixes files where this length is
exceeding.

1. https://luacheck.readthedocs.io/en/stable/warnings.html#line-length-limits
---
Changes v2:
- Added fixes according to comments by Sergey Kaplun.
- Reduced a max length of lines with comments (80 -> 66).
- Fixed warnings triggered by reducing max limit of lines with
  comments.

I suggest the following patch instead to prevent the warning only for
necessary part of the IR dump:

Thoughts?

I've no objections, applied.
