patch 9.1.0537: signed number detection for CTRL-X/A can be improved
Problem: signed number detection for CTRL-X/A can be improved
(Chris Patuzzo)
Solution: Add the new "blank" value for the 'nrformat' setting. This
will make Vim assume a signed number only if there is a blank
in front of the sign.

+ Using CTRL-X on "8" in "Carbon -8" results in "Carbon -9"
+ (because -8 is preceded by whitespace. If "unsigned" was
+ set, it would result in "Carbon -7").
+ If this format is included, overflow is prevented as if
+ "unsigned" were set. If both this format and "unsigned" are
+ included, "unsigned" will take precedence.

Numbers which simply begin with a digit in the range 1-9 are always
considered decimal. This also happens for numbers that are not
recognized as octal or hex.
