Bug#308865: vim-common: matchit.vim problems with fortran 90 module procedure statements

[Kamaraju Kusumanchi]

Package: vim-common
Version: 1:6.3-071+1
Severity: normal

To reproduce the bug consider the Fortran 90 code attached in the end. This is
a valid Fortran 90 program which compiles and runs just fine.

Open the file in (g)vim and source /usr/share/vim/vim63/macros/matchit.vim

Now place the cursor on line 14 and press %. The cursor goes to the line 18.
This is the intended behaviour of the matchit plugin. But If the cursor is
placed on line 1 and % is pressed then nothing happens. Ideally module and end
module statements (line 1,19 respectively) should match with each other with %.
This is not happening because there is a match between line 4 and line 19 due to
the occurence of the word module in line4.


$cat -n matchitbug.f90
     1  module match
     2    implicit none
     3    INTERFACE print_a_number
     4      module procedure print_real, print_integer
     5    END INTERFACE print_a_number

     8  subroutine print_real(r)
     9    implicit none
    10    real :: r
    11    write(*,*) 'real number = ', r
    12  end subroutine print_real
    13
    14  subroutine print_integer(i)
    15    implicit none
    16    integer :: i
    17    write(*,*) 'integer = ', i
    18  end subroutine print_integer
    19  end module match
