[PATCH] git-clone: better error message if curl program is missing

From: Gerrit Pape <pape@smarden.org>

Message-ID: <20070907171400.28590.qmail@d780fac1e27de6.315fe32.mid.smarden.org>

If the curl program is not available, and git clone is started to clone a repository through http, this is the output

 Initialized empty Git repository in /tmp/puppet/.git/
 /usr/bin/git-clone: line 37: curl: command not found
 Cannot get remote repository information.
 Perhaps git-update-server-info needs to be run there?

This patch improves the error message by testing for availability of the curl program before running it, the error output now is

 Initialized empty Git repository in /tmp/puppet/.git/
 The curl program is not available

Adrian Bridgett noticed this and reported through
