Subject: bin/get-fixes-pick-list.sh: bring back the warning
X-Git-Tag: upstream/18.1.0~9827
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b7af0ddfef882b2e82db953ff0d3e57843604525;p=platform%2Fupstream%2Fmesa.git

bin/get-fixes-pick-list.sh: bring back the warning

We warn again if there are more than one line with the "fixes:" tag.

The warning is silenced when the commit has already landed or each
fixes tag reference a commit that is in branch.

v2:
 - Warn if any of the fixes tags has not landed (Emil)

v3:
 - Remove unnecessary head command
 - Clarify commit message (Emil)
 - Skip already picked commits sooner (Emil)
