Subject: Default for Completion is *no* filename completion
X-Git-Tag: v1.003015~24
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=fd81abf13426f0eea8915247e7909d20a4f98661;p=p5sagit%2FDevel-REPL.git

Default for Completion is *no* filename completion

The default for the Completion plugin is now to specifically
disable the standard Term::ReadLine::Gnu and Term::ReadLine::Perl
filename expansion when it is loaded.  A new attribute
do_readline_filename_completion is available to re-enable
the Term::ReadLine functionality.
