Truncate some very long lines and leave the r-process function if Zmax is too small.
The backup '*.*~' files were not removed recursively by veryclean.

It seems that emacs notices that it's a git repo and stops making backups.
Also *.*~ will miss some files so change to *~.
Made a mistake in commit 19f1a76 with what the variables actually represent.
Again, as with commit 19f1a76, use more descriptive variable names in the postscript file.
