// Support for creating column-formatted strings. Columns which exceed their
// size limit are truncated. Columns are collected into 'groups', each of
// which starts at a particular location. This allows things such as
// right-justification of text. If one column group overlaps another, the
// conflict is resolved by adjusting the column which is situated farthest to
// the right (by moving it farther to the right).
//
// Right-justification is now handled (somewhat hackily) by columnify; to
// use it, set the start_off to something negative. The group will be aligned
// so the the right edge of the column is start_off+1 characters from the
// right-hand screen edge -- so to align something exactly with the right-hand
// edge of the screen, set start_off to -1.
