One reason that jumps out at me is that the pattern character, '.' won't normally match a newline.
If you append the '/s' modifier to your regexes it changes the behavior such that '.' will match newlines (see perlman:perlre). Try this:
if ( /if.*?\{/s .. /.*?\}.*?else/s ) {
s/\{//;
s/\}//;
}
This, of course, assumes that you have the entire if-else construct in $_ to begin with.
Update: fiddled with text.
Update 2: removed extraneous $_ bindings in substitutions and escaped the curly braces (nice catch, Zaxo).
