Avery Pennarun c03543dbe2 version.sh: keep the short version even if there are patches on top.
Instead of reverting to 0.0.0, keep the same version number (eg. 1.2.4)
but add an extra suffix with the change count,
eg. 1.2.4-6-tb35d95ad7-gcb8be72e6. This avoids the problem where a
small patch causes the code to report a totally different version to
the server, which might change its behaviour based on version code.
(The server might enable various bug workarounds since it thinks
0.0.0 is very old.)
