[Orgmode] Possible bug?

[Christos Chryssochoidis]

Hi,

I wanted to ask about a behavior that doesn't seem right to me, if
it's indeed a bug or rather some misunderstanding of mine.
Trying to update the effort time of a task with C-c C-x C-e, and using
the syntax +HH:MM, I've found that instead of augmenting the effort
time by that amount of time, org-mode just set the effort time to that
amount; not relatively to the old effort time, but absolutely as if
the sign (+/-) didn't exist.
I modified just one line in org-clock.el and now it seems to work as I
expected. My modification follows below.

Thanks to all developers of org-mode!
