Me too.  On ruby 1.7.0 (2001-04-02) [i686-cygwin] checked out from CVS and
built this morning I get this:
     s = "yadda'yadda'yadda"
     s.gsub(/'/, "\\'")              >>     yaddayadda'yaddayaddayaddayadda
     s.gsub(/'/, "\\\'")             >>     yaddayadda'yaddayaddayaddayadda
     s.gsub(/'/, "\\\\'")            >>     yadda\\'yadda\\'yadda
     puts s.gsub("'", "\\\\'")       >>     yadda\'yadda\'yadda

Why the difference between s.gsub(...) and puts s.gsub(...)?
     t=s.gsub(/'/,"\\\\'")           >>     "yadda\\'yadda\\'yadda"
     t.type                          >>     String
     puts t                          >>     yadda\'yadda\'yadda

Note that the result for t -- and for s.gsub(/'/,"\\\\'"), directly -- is
displayed in double quotes.  The backslash is a special character that gets
represented within a String as escaped; hence the second "\" in the visible
representation.  When presented by puts, the output does not have to be
represented as a quoted string.

At least I think this is what's going on here.

Ruby newbie,           ... Hey! That's poetry in motion!
