Subject: bash-completion: use a better definition of __contains_word
X-Git-Tag: v207~207
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=a72d698d0d9ff9c158155b44cdc77376df31a317

bash-completion: use a better definition of __contains_word

- scope the iterator var
- use the correct, quoted, non-expansion prone positional parameter
  notation
- prevent expansion on RHS of comparison
- remove unneeded explicit returns.

This really should be defined only once...
