vim-patch:9.1.0537: signed number detection for CTRL-X/A can be improved (#29590)

Browse Source 
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.
          (distobs)
