PATCH: 3.0.6-pre-3: minor tweaks after last patch

[Wayne Davison]

These simple changes follow-up my just-released patch for 3.0.6-pre-3:

I failed to include a minor tweak from my history changes that made
the hasher() function use a slightly different character-casting
syntax (since I have a dim recollection that the new way avoids a
sign-extension problem on certain systems).

Also, I failed to notice that I left a trailing period on a couple
of debug error messages (the new strings now match pws-20).
