When the input kernel to the Convolve program has a single element, it crashes
by complaining about non-equal number of dimensions! Eventhough they do indeed
have the same number of dimensions:


$ astarithmetic 100 100 2 makenew -oimg.fits
$ echo 1 | astconvertt -okernel.fits
$ astconvolve img.fits --kernel=kernel.fits
astconvolve: input datasets must have the same number of dimension


$ astfits kernel.fits -q
0      CONVERTTYPE-CONFIG no-data         0   n/a
1      n/a                float64         1x1 n/a


$ astfits img.fits -q
0      ARITHMETIC-CONFIG no-data         0       n/a
1      n/a               uint8           100x100 n/a


I am working on the fix to this bug.
