Modify count_spaces() to take a third parameter "end" that will make the function return when the end is reached. This lets the caller pass a pointer to non nul-terminated sequence of characters. Rename count_spaces() to count_spaces_until() and reinstate count_spaces(), this time based on count_spaces_until(). Use count_spaces_until() to recalculate current column when going through a comment just before the fragment which decides if current line of the comment should be wrapped. This move simplifies this code by eliminating the need for keeping the column counter up to date every time e_com is advanced and also reduces spread of code that has to know how many columns a tab will produce. Deduplicate code that decided if a comment needs a blank line at the top.
