Mostly readability of the code, as I see it.
One source line instead of 2, 3 or 4 lines.

And XC8 generates different assembler code.
For the one-bit-at-a-time format it always genereates
separata BCF/BSF instructions. For the combined format
it generates AND/OR instructions (with for setting
"0000" or "1111" is shorter then 4 BCF/BSF).

I think I wrote that I didn't found any. You need the
"REGISTERbits." format, it seems.

In MPLABX I only have to type the dot and the dropdown list
of available options opens automaticly.
