++
++ For example, when editing assembly language files where statements
++ start in the 8th column and comments in the 40th, it may be useful
++ to use the following: >
++ :set varsofttabstop=8,32,8
++ < This will set soft tabstops at the 8th and 40th columns, and at every

++ separated by commas. Each value corresponds to one tab, with the
++ final value applying to all subsequent tabs. For example: >
++ :set vartabstop=4,20,10,8
++ < This will make the first tab 4 spaces wide, the second 20 spaces,
