build: make install in "/doc" failed if the destination dir contained spaces
This and the following commits try to add the necessary quoting in the build
scripts to make the process more robust.
The target for now is rendering "make deb" successful even when the base
directory contains spaces (eg. "/opt/mercu rial").
The build process should succeed without scattering files in spurious
directories (eg.: "/opt/mercu/usr/bin/hg").

issue5540)
Test contributed by Matt Harbison

stripped changsets), but if the branch differs from wdir's, try to find another
parent of stripped commits that is on the same branch.
