+For decimals a leading negative sign is considered for incrementing/
+decrementing, for octal and hex values, it won't be considered.
+To ignore the sign Visually select the number before using CTRL-A or CTRL-X.

For numbers with leading zeros (including all octal and hexadecimal numbers),
Vim preserves the number of characters in the number when possible. CTRL-A on
"0077" results in "0100", CTRL-X on "0x100" results in "0x0ff".
