Comment (by nacin):

 In general, I'd argue that `/U` (PCRE_UNGREEDY) should not be used. It
 isn't natural to read a regular expression as if things are un-greedy;
 using `?` to make something lazy/reluctant/nongreedy is going to be easier
 to understand.

 `/U` is also sometimes misread as `/u` which is for UTF-8 (and also should
 not be used in many cases).
