Subject: 26.1; ada-mode 6.2.1 incorrect indentation with partial parsing
Date: Wed, 11 Dec 2019 15:41:20 +0100

X-Debbugs-CC: ada-mode-users <at> nongnu.org
Package: emacs, ada-mode
Version: 26.1
Severity: minor

When we visit one of our larger source files which compiles and
is not yet modified, move point to after a "begin" keyword and hit
RET, ada-mode incorrectly re-indents the "begin" keyword and the
next (new and empty) line.

Expected:

      declare
        procedure Action (Airspace : Env_Volume.T; Info : 
Curtain.Profile.Index.T) is
          [elided]
        end Action;
        procedure Action_Airspaces is new 
Curtain.Profile.Index.Visit_Unskipped_Airspaces_G;
      begin* -- point is here initially; hit RET
        * -- point should come here after RET
        Airspace_Entry_Times_Set.Empty (Airspace_First_Entry_Times, 
Profile_Query);
        -- The query causes the set to be initialised or resized if 
necessary.
        Action_Airspaces (Profile.Curtain, Profile_Query);
      end;

Actual:

      declare
        procedure Action (Airspace : Env_Volume.T; Info : 
Curtain.Profile.Index.T) is
          [elided]
        end Action;
        procedure Action_Airspaces is new 
Curtain.Profile.Index.Visit_Unskipped_Airspaces_G;
        begin -- incorrectly changed indentation after RET
          * -- point is here after RET
        Airspace_Entry_Times_Set.Empty (Airspace_First_Entry_Times, 
Profile_Query);
        -- The query causes the set to be initialised or resized if 
necessary.
        Action_Airspaces (Profile.Curtain, Profile_Query);
      end;

If I forcibly disable partial parsing in this file, the bug disappears.
