Bug in "changes" tab in Gitlab

[Ömer Sinan Ağacan]

Hi,

I think there's a currently a bug in "changes" tab in gitlab. If you look at [1]
it shows as if I added a new line in `Main.hs`, but actually I just changed one
word:

    diff --git a/utils/genapply/Main.hs b/utils/genapply/Main.hs
    index 71b84fde79..7038dc5c09 100644
    --- a/utils/genapply/Main.hs
    +++ b/utils/genapply/Main.hs
    @@ -903,7 +903,7 @@ genStackApply regstatus args =
     --
     -- These code fragments are used to save registers on the stack at a heap
     -- check failure in the entry code for a function.  We also have to save R1
    --- and the return address (stg_gc_fun_info) on the stack.  See
stg_gc_fun_gen
    +-- and the return address (stg_gc_fun_info) on the stack.  See __stg_gc_fun
     -- in HeapStackCheck.cmm for more details.

I'm guessing that Gitlab is confused by the `---` prefix in the diff.

I was going to report it but I realized that we're not using the latest version
(the "help" page says "update asap"), so perhaps we should try updating first?
