9516cd9ee3 feat(library/tactic): 'exact' tactic report unsolved placeholders in nested expression 
Actually, the elaborator is the one reporting the unassigned
placeholders. The 'exact' tactic just makes the request.
To implement this feature we had to extend the elaboration interface
expected by the tactic framework.

fe638f0ee7 fix(emacs/lean-flycheck): fix bug in advice for lean-flycheck-try-parse-error-with-pattern 
I provided an "advice" for 'flycheck-try-parse-error-with-pattern'
function to change its behavior, namely to increase error-columns by
one.

Bug
===

The problem is that it doesn't consider the case where the pattern is
not matched and ends up with "err = nil". For this case,
"(flycheck-error-column err)" generates an exception if executed. The
whole error parsing process stops immediately.

This causes a problem when we have more than one error-patterns, which
is the case when we enable 'error' and 'warning' patterns.

Fix
===

Fix is simple: check err before executing (flycheck-error-column err)

-            (col (flycheck-error-column err)))
+            (col (and err (flycheck-error-column err))))
