Vl-col-after-printing-chars

Figure out where we'll be after printing some characters.

Signature

(vl-col-after-printing-chars col chars) → new-col

Arguments

col — Current column we're at.
    Guard (natp col).

chars — Characters we're about to print, not yet reversed.
    Guard (character-listp chars).

Returns

new-col — Column we'll be at after printing chars.
    Type (natp new-col).
