Fixes in 1998 html files

This includes some notices to those who wish for a greater challenge.

In the 1998/schweikh3 the man page (and its copy to demonstrate the
entry) have been updated slightly but only in comment (move 'or' from
the command suggested to render it in text to its own line before the
next command also in comment).

The bugs file was updated for an entry or two.

 ## Author's remarks:
 
-In literary circles, there is a poetic form called a "lipogram",
-which is a poem in which a specific letter has been distinctly
-avoided.  This principle can be applied in other ways.  For
-instance, in this paragraph, the vowel which immediately follows
-`t` in the alphabet is nowhere to be seen.  There is even an
-entire novel (E. V. Wright's "Gadsby") in which no word contains
-the letter `e`.

 The IOCCC has been no stranger to this concept.  Several winning entries from
 years past have accomplished interesting feats while completely avoiding the use
 of certain C constructs thought to be essential (e.g.,

 In continuing with this fine tradition, this program suggests to the ANSI
 committee some new practical simplifications for the C language.  For instance,
