#14 ALT-del del's character in search field

[Jan Warnking]

When deleting the current database field using "Alt-Delete",
and the cursor in the search field is not at the end of the
line, the character behind the cursor gets deleted, just as if
one was pressing "Delete" alone.
Of course, the current entry is deleted, too, as it should.
