bug#41577: automatic alignment

Hi folks,

Finding a good alignment appears to be a pretty complex task, esp.
for some RAID devices, so I wonder if this could be better supported
in parted? The current

[bzzzzzzzz] The resulting partition is not properly aligned for best performance.

for all 2**n is *more* than annoying. For my lsi RAID I had to use

Number  Start  End           Size          File system  Name    Flags
  1      1536s  46880782847s  46880781312s               export

following the guidelines on [1].

Obviously the align-check option has some deeper knowledge about
a good alignment, but it doesn't tell. :-(
