It's kind of nice to have real English single quotes is general text 
(`these' produce real quotes). They print nicely in PostScript for 
example. But yes, this causes some problems if a man page writer - be 
it a machine or human - is not aware of the difference between English 
quotes and shell quotes. There is logical difference even if they 
happen to appear the same on some systems. It's very easy to write 
something like this to man page's general text: "The string can be 
enclosed in single (') quotes." And now we have English right single 
quotation mark (and apostrophe) in man page, not a shell single quote.
