Hello,

I've just finished reading the gm4 1.0.3 document (dated November 15th, 1992)
and have some minor fixes for the doc (which I hope are correct):

1. Section 7.6 (Deleting a macro, page 17):
   It says "If there is no previous definition, popdef does nothing", which I
   think you ment to read "...popdef behaves like undefine".  Anyway, I
   didn't expect the behaviour demonstrated in the example from this
   description.

2. Section 8.3 (Loops and recursion), at page 23:
   Looks like the second line in the definition of the _forloop macro
   is intermingled, it prints:

   '$4''ifelse($1, '$3', ,

   while I think the third quote on the line (the one just before the ifelse)
   should be a coma,  am I right?

3. Section 10.3 (Changing comment delimiters, page 30) says:

   "..., much as it they were quoted strings."

   's/as it/as if/' ?

4. Section 12.1 (Diverting output), page 35 says:

   "If output is diverted to an non-existent diversion, ...",

   's/ an / a /' ?

5. Section 14.2 (Evaluating integer expressions, page 45) says:

   -     Unany minus

   's/Unany/Unary/'


Thanks for a wonderfull piece of software.
