bug#31945: 27.0.50; Readability of format docstring

[Andreas Röhler]

C-h f format RET


Docu of format arguments starts commonly with argument in column 0.
%x however starts after comma inside a line:

"%s means print a string argument.  Actually, prints any object, with 
‘princ’.
%d means print as signed number in decimal.
%o means print as unsigned number in octal, %x as unsigned number in hex.
"

Suggest to move docu of %x to column zero too.
Maybe consider to sort arguments alphabetically.
