Howto get “minimal matching” on a particular
\\(.*\\) sub expression, ie. howto write a non-greedy regular expressions as in Perl
A strict POSIX implementation will still match the above greedily, but most backtracking implementations will do the above match non-greedily, just as
(.*?) would. The above hack works in Emacs versions earlier than 21.1.
In Emacs 21.1 and later versions Perl-like non-greedy syntax (.*?) has been implemented.
In either case the * and + special characters can be used to create a non-greedy regexp.
