Subject: scripts/getver.sh: Use 'git-rev-parse' to detect if tree lies in Git repository
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=562633267951ffa54826a824dea8a87a3cce872d;p=openwrt%2Fsvn-archive%2Farchive.git

scripts/getver.sh: Use 'git-rev-parse' to detect if tree lies in Git repository

Path to the Git repository directory can be overriden by using the '$GIT_DIR'
environment variable. This patch improves detection of Git repository by using
'git-rev-parse', which respects '$GIT_DIR' environment variable, instead of just
checking the existence of '.git' directory.
