The help actually says:
breaks: one of:
* a vector giving the breakpoints between histogram
cells,
* a single number giving the number of cells for the
histogram,
* a character string naming an algorithm to compute the
number of cells (see 'Details'),
* a function to compute the number of cells.
In the last three cases the number is a suggestion only.
The last sentence explains your observation.
BTW, this was recently discussed:
