Subject: [PATCH 1/3] Set the version number.

Store it in a separate file so OS packages and 'make install' (issue #177) can
reuse it.

Subject: [PATCH 2/3] versionstamp: Handle NO_FUNCTION_ARGZERO.

Sourcing zsh-syntax-highlighting.zsh without FUNCTION_ARGZERO doesn't work (for
reasons unrelated to this branch), but now errors out gracefully.  The failure mode
before this branch was:

    zsh-syntax-highlighting: highlighters directory '/usr/local/bin/highlighters' not found.

where /usr/local/bin is dirname() of the zsh binary.
