[metapost] "bugs" in the MetaPost reference manual 1.000

[Лидовский Владимир]

Hello!

I've just translated A User's Manual for MetaPost into Russian. I am 
ready to
send it (1MB pdf, 580KB src) to any address if it would be useful.

I've also found several (exactly 17) misspellings in version 1.000 of 
the original
manual. I've attached log produced by `diff' with "bugs" descriptions
and locations.

Regards,
Vladimir Lidovski

P.S. `diff' output with comments
#for version 1.000 of the manual.
