Subject: bash-completion: _tilde calls compgen w/o "--" argument protection

Date: Tue, 21 Oct 2014 11:22:49 +0200

Package: bash-completion
Version: 1:2.1-4
Severity: minor

Hi,

when tilde-expanding in function _tilde(), the following line

  COMPREPLY=( $( compgen -P '~' -u "${1#\~}" ) )

does not protect $1 by preceding it with "--", which means that if $1 starts
with ~- (the $OLDPWD tilde-prefix), compgen will try to interpret characters
after the - as options.

Example: tab-completion of of "mv ~-o":

  $ mv ~-obash: compgen: -o: option requires an argument
  compgen: usage: compgen [-abcdefgjksuv] ...

Nothing too terrible, but still ugly, and easily fixed.

Thanks and have a nice day,
Nikolaus
