incorrect indication with `block` as variable or label

[folk85]

Describe the bug If we define the label or variable with name block, then it would indicate end of routine as incorrect end.

To Reproduce If I use the following command fortls --debug_filepath test_rename_block.f90 --debug_rootpath . --debug_full_result --debug_log I get info:

DEBUG:fortls.constants:REQUEST None None
INFO:fortls.constants:fortls - Fortran Language Server 0.1.dev986+g8f11b57 Initialized

The example of code:

module test_rename_block
    implicit none
contains

    subroutine block_test01()
        integer :: i 
        block: do i = 1, 1 
            write(*, *) "use label with name block : ", i  
        end do block
    end subroutine block_test01

    subroutine block_test02()
        integer :: block 
        do block = 1, 1 
            write(*, *) "use index name block :", block 
        end do
    end subroutine block_test02

end module test_rename_block

program driver
    use test_rename_block 
    implicit none
    call block_test01()
    call block_test02()
end program driver

Expected behavior If we use variable or label name as block the fortls won't expect end block part and must show end of subroutine/function correctly.
