[PATCH 1/1] build: handle special characters when building from git

[Manuel Bachmann]

When building from a git repository, in Makefile.am, the
macro creating the "src/git-version.h" file will fail
if the last commit subject contains a special character
such as ". Escape characters so that the output string
is, at worst, empty.
