Details:

Octave returns wrong tick labels when limits are set manually:


plot (1:10)
xlim ([.5 10.5])
get (gca, 'xtick')
get (gca, 'xticklabel')


The displayed xlabels are correct, i.e [2 4 6 8 10], while the returned values
for "xtick" and "xticklabel" properties are consistently wrong: [0 2 4 6 8 10
12]. These are the labels we would have obtained if xdata had actually
extended from 0.5 to 10.5 and the xlimmode had been "auto".

I could check in ML 3013a that displayed and returned values are consistent,
i.e. [1 2 3 4 5 6 7 8 9 10].

I *wouldn't* expect that Octave follows ML exactly (i.e. increments of 1
instead of 2), but I do expect displayed and returned values to be consistent
as in ML.
