Yes, because the changeset to be uploaded is already computed. There
was some discussions here about adding a preprecommit hook. I don't
remember the conclusion.

A solution would be to use a wrapper script to commit.

Not sure to understand your need, but doesn't a build script
generating a source file containing the version info do the job (as
tla itself does to implement "tla --version") ?

Another solution is to use a "timestamp" feature (or equivalent) from
your editor to do this.

Yes, you'll get conflicts on this line on each merge.

Also, if your hook modifies unmodified files, you'll get huge revision
libraries, and bigger changesets.
