What do you think?
I already check for an empty string in Vim 7. Not for a string that is white space. I wouldn't know how to set $SHELL to all white space without explicitly doing so. It doesn't make sense, we also don't check for leading or trailing white space in the $SHELL value. Using environment variables should be consistent. I think most places now check for an empty string. I think that's sufficient. - Bram -- He who laughs last, thinks slowest. /// Bram Moolenaar -- [EMAIL PROTECTED] -- http://www.Moolenaar.net \\\ /// Sponsor Vim, vote for features -- http://www.Vim.org/sponsor/ \\\ \\\ Project leader for A-A-P -- http://www.A-A-P.org /// \\\ Buy LOTR 3 and help AIDS victims -- http://ICCF.nl/lotr.html /// -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
