Subject: Support squashing patches in patch generation
X-Git-Tag: 0.10~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=94d63cb5a72ffce379b93c4ba028454cfa4a1be5;p=tools%2Fgbs.git

Support squashing patches in patch generation

Add new command line and config file option to squash commits in patch
generation into a one monolithic diff. One usage example could be e.g.
in linux kernel to squash commits between base version and stable branch
head into one .diff.

This patch directly facilitates git-buildpackage and just passes the new
option to it.

Command line option takes preference over the config file.
