gh-106656: Remove --emit-line-directives from regen-cases

[gvanrossum]

If you prefer to see #line directives in generated_cases.c.h, run make regen-cases CASESFLAG=-l. But please don't commit the result.

• Issue: Let's not generate #line directives in generated_cases.c.h #106656

[gvanrossum]

I plan to merge this later today, after fixing the merge conflict.

[gvanrossum]

(A side effect will also be fewer merge conflicts on the generated files.)

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false
