Subject: When we are using dpkg-buildpackage to clean before using it to also do the build... 
X-Git-Tag: debian/1.1~15
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=dgit.git;a=commitdiff_plain;h=dbb093b1db7b27bf922f6ad58576cab4fbc342cf

When we are using dpkg-buildpackage to clean before using it to also do the build, let it do its cleaning thing as part of its run, rather than running it twice.  When we are _not_ supposed to be using dpkg-buildpackage to clean, but we are running it to do the build, pass -nc.

   * Rename `git-build' operation to `gbp-build' to make it clearer what
     it's for.  Keep the old name as an alias.
