that's a valid point. the manual-page claims to be compatible to
preg_replace() but here it isn't fully.

nope, because the $1 is subject to smarty's variable interpolation
inside double-quotes *before* the plugins gets the parameters.

not really, you mean

{$entry.file|regex_replace:"'.*/([^/]+)$'":"\1"}

also 

{$entry.file|regex_replace:"'.*/([^/]+)$'":'$1'}

works

BTW: for this particular case i suggest {$entry.file|basename} over
regex_replace.
