Mark Lodato ca209065f3 completion: fix zsh check under bash with 'set -u' ... Commit 06f44c3 (completion: make compatible with zsh) broke bash compatibility with 'set -u': a warning was generated when checking $ZSH_VERSION. The solution is to supply a default value, using ${ZSH_VERSION-}. Thanks to SZEDER Gábor for the fix.
