Ugh, just got bitten by trying to replace ' w/ \' in a string (backslash
apostrophe).

Turns out that \' is a regex interpolator, just like \1, \2, so
"a'b'c'd".gsub("'","\\'") did not work, nor did it with the 2nd param as
'\\\''.
The magic incantation from trial and error is:
"\\\\\'"

Yuck!

Online documentation could certainly be improved.
