refactor: more idiomatic syntax for if h: ( #5567 )
...
https://github.com/leanprover/lean4/pull/5552 introduced a fair number
of `if h:`, but the slightly preferred style is `if h :`, with a space,
so here goes a quick `sed`.

fix: do not lift (<- ...) over pure if-then-else ( #3820 )
...
Now, only `(<- ...)`s occurring in the condition of a pure if-then-else
are lifted.
That is, `if (<- foo) then ... else ...` is ok, but `if ... then (<-
foo) else ...` is not. See #3713
closes #3713
This PR also adjusts this repo. Note that some of the `(<- ...)` were
harmless since they were just accessing some
read-only state.

fix: allow generalization in let ( #3060 )
...
As suggested by @kmill, removing an unnecessary `let` (possibly only
there in the first place for copy/paste reasons) seems to fix the
included test.
This makes `~q()` matching in quote4 noticeably more useful in things
like `norm_num` (as it fixes
https://github.com/leanprover-community/quote4/issues/29 )
It also makes a quote4 bug slightly more visible
(https://github.com/leanprover-community/quote4/issues/30 ), but the bug
there already existed anyway, and isn't caused by this patch.
Fixes #3065
