From: Mark Lodato Date: Thu, 28 Oct 2010 01:08:21 +0000 (-0400) Subject: completion: fix zsh check under bash with 'set -u' X-Git-Tag: v1.7.4-rc0~159 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ca209065f3cc3462eb0ae6090f6b13f38aa2114c;p=git.git 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.
