Subject: Only initialize REPO_SOURCE_DATA if Bash supports associative arrays.
X-Git-Tag: v0.3~27
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=9ff9741fe13708880f9130cf81d06578605b6c22;p=dotfiles-framework.git

Only initialize REPO_SOURCE_DATA if Bash supports associative arrays.

We already bail out if the user tries to clone using wget.  This
commit just avoids pestering the user with the 'declare' error
message.
