- * The editor uses a temporary file for files being edited, in a structure
- * similar to that of ed.
- * Lines are represented in core by a pointer into the temporary file which
- * is packed into 16 bits. 15 of these bits index the temporary file,
- * the 16'th is used by by redisplay. The parameters below control
- * how much the 15 bits are shifted left before they index the temp file.
- * Larger shifts give more slop in the temp file but allow larger files
- * to be edited.
