[cl-ppcre-devel] missing replacement

[Mario Maio]

If i try this regexp

(cl-ppcre:regex-replace-all " d {1-3}'" "la presa d 'aria" " d'" 
:preserve-case t)

I don't get the expected replacement (remove the space before the 
apostrophe)

"la presa d'aria"

whereas Regex Coach works as expected.

Thanks.

Mario
