Please, notice the chunk number 8 in file "doc/tutorial/tweaking.texi".
It changes a part from the "myfirst.tr" listing.
Actually there is no PppHeader in MacRx tracing source. (probably because
PppHeader has already been removed by the time of MacRx tracing event)

Applied.  Changeset:   f4d74e20ad78

I went ahead and applied this (better late than never).  Thanks a lot for the
time you spent on this, Andrey.

One comment I have is about punctuation in quotations.  You "fixed" several
instances of language that looked like

  "some words," 

to 

  "some words",

In American English, the first method is considered correct and the second is
considered incorrect (the reasons date back hundreds of years to typesetting
concerns about the lifetime of small metal type).

In other less important dialects like "The King's English," which I believe is
spoken on an island off the coast of France (yes, I'm joking), the second
version is considered better.

You can have fun thinking about what this small thing says about the priorities
of Americans and the English, but it's probably wise to let things like this
lie rather than begin "correcting" them.

Craig, thank you for your clarification!
I'm sorry for these stupid changes about punctuation in quotations.
I can revert them to conform to American style if you appreciate my work.:)
I've read something more about punctuation in [1], so I hope to avoid such
mistakes in the future.
