Since all messages marked for translation contain permutable format
strings, we can add checks for enforcing them.
The syntax check does not catch all cases as it only checks format
strings between _(" and the first ". In other words messages where \"
appears before the first format string or multi-line messages where the
first format strings is not in the first line will not be checked. On
the other hand, it's run automatically by "meson test".
check-pot.py python script will detect all incorrect format strings, but
it's not as easy to use as it requires libvirt.pot to be regenerated and
this does not happen during a standard build. The following steps are
needed to check messages with check-pot.py:
meson compile libvirt-pot-dep
meson compile libvirt-pot
meson compile libvirt-pot-check
Don't forget to revert changes to libvirt.pot if you run these commands
locally as we don't want each patch series to update libvirt.pot.
Shell scripts (tools/libvirt-guests.sh.in is the only one currently)
need to be exempt from this check as shell's printf function does not
understand the permutable format strings.
