//strdetab.h
/*
  strdetab takes a null-terminated string in_buf,
  possibly containing tab characters and copies it to
  out_buf, expanding the tab characters as it goes.
  Copying stops when max_line_length characters have
  been placed in out_buf or when in_buf has been
  completely copied. out_buf is null-terminated
  (The '\0' is in addition to max_line_length).
  If char_line_length is not NULL, then
  *char_line_length is set to the number of characters
  in out_buf (the equivalent of strlen).

  The way that the tabs are expanded is determined by
  no_of_tabs and tab_stops. tab_stops is an array
  of size no_of_tabs, i.e. indexed 0 to no_of_tabs - 1.
  Each entry in tab stops is a tab position.
  If no_of_tabs == 1 then the first entry in
  tab_stops is used to specify the position for all
  tabs in the line, at intervals of tab_stops[0].

  If tab_stops is exhausted, then tabs are replaced by spaces.

  strdetab returns a pointer to out_buf.
