Image link deletion leaves stray square brackets

[Peter Bowman]

Image links seem to not be correctly parsed if they include square brackets in their captions, especially in such a configuration as the following:

[[File:filename.jpg|thumb|[1]]]

See this edit on es.wiktionary.

The regex on line 350 takes into account the presence of wikilinks (those in double square brackets):

$pattern_link = "\[\[\s*$pattern_file.*?(\[\[[^\]\[]+?\]\].*?)*\]\]" ;

Something like this should include single square bracket links (and plain text like [1]) as well:

\[\[\s*$pattern_file(\[\[.*?\]\]|\[.*?\]|.*?)*\]\]
