This uses a normal c array to store parent sha's. That means that we
save a lot of room, as they are only 20 bytes rather than 40 + the cost of
an NSArray and the NSStrings.
The ref functionality is somewhat weird right now, in that
some parts of the code require a nil array when there are no
refs. So, we add a good removeRef accessor to keep track of this
This should make the GUI more responsive by allowing the diff
to be read in the background. This assumes that
[PBGitCommit details] is threadsafe, so we should keep it that
way.
This makes the PBGitRevisionCell a bit nicer by retrieving all values
from the PBGitCommit object itself, and using another NSTextFieldCell to
draw the text.
This mean that PBGitGrapher now stores its information in the PBGitCommit's,
rather than in a custom grapher array. Also, because we don't need the
grapher to display refs anymore, the ref labels are also displayed when
using path limiting (for example, 'gitx -- Makefile').
This uses the C fgets() over the weird readLine implementation I found.
It speeds up the rev-parsing significantly: we went from ~4.5 seconds
on the git.git repo to ~0.95 seconds. And that's with the secret new date
parsing!
