A little explanation:
This is the same a what Franklin52 suggested, just the technique of extraction the version string is different. The result is put in the variable revnr. The return code is the return code of the assignment and not that of the checkout so it is always 0. So in fact the first && is bogus and a "; " could also have been used instead. Since we do not have a return of the checkout we need to test the result:
If the variable is non-empty then the checkout was successful so we can go ahead with the tar.
As to your question about the information, IMO an O'Reilly book on your favorite shell (hint: pick ksh, pick ksh...) is usually a good place to start, but I am sure there are plenty of online resources...

times
times(1) User Commands times(1)NAME
times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
