[CC'ed Duy for ideas, as the "%>|(ALIGN)" thing is his invention]
If you imagine an entry for a commit in the "git log" output as a
rectangle that has its commit log message, "--graph" draws a bunch
of lines on the left hand side and place these rectangles on the
right of these lines. Space allocated to each of these rectangles
may and do begin at a different column. For example, here is an
output from
$ git log -12 --graph --oneline

I can understand why you would want to include the varying width of
the river on the left hand side in the "space allocated for the
commit", and under that mental model, the patch makes sense, but at
the same time, it is also a perfectly good specification to make
"%>|(20)%h" pad "%h" to 20 columns from the left edge of the space
given to the commit.
I have a suspicion that 50% of the users would appreciate this
change, and the remainder of the users see this break their
expectation. To avoid such a regression, we may be better off if we
introduced a new alignment operator that is different from '%>|(N)'
so that this new behaviour is available to those who want to use it,
without negatively affecting existing uses.
And the use of ctx->graph_width in the hunk below would be the only
thing that needs to be changed (i.e. added to occupied only when the
new alignment operator is used).
Other than that, this round of reroll looks ready for 'next'.
Duy what do you think?
Thanks.
