 /*
- * NAME:
- *     pr_comment
+ * Scan, reformat and output a single comment, which is either a block comment
+ * starting with '/' '*' or an end-of-line comment starting with '//'.
  *
- * FUNCTION:
- *     This routine takes care of scanning and printing comments.
+ * Try to keep comments from going over the maximum line length.  If a line is
+ * too long, move everything starting from the last blank to the next comment
+ * line.  Blanks and tabs from the beginning of the input line are removed.
  *
  * ALGORITHM:
  *     1) Decide where the comment should be aligned, and if lines should
  *        be broken.
  *     2) If lines should not be broken and filled, just copy up to end of
  *        comment.
- *     3) If lines should be filled, then scan thru input_buffer copying
- *        characters to com_buf.  Remember where the last blank, tab, or
- *        newline was.  When line is filled, print up to last blank and
- *        continue copying.
- *
- * HISTORY:
- *     November 1976   D A Willcox of CAC      Initial coding
- *     12/6/76         D A Willcox of CAC      Modification to handle
