Today I wanted to discover the author, commit id, and the date for a commit that created a particular line in a file (the restore_cmap1() line in examples/python/xw08.py which has no C counterpart). After a bit of searching I discovered the "git blame" command which did exactly what I wanted. So I was getting all enthused about this great new capability possible with git, when I checked back with subversion. It turned out subversion has the similar "svn blame" capability (albeit with much more limited features than "git blame") which I was completely unaware of when using subversion all those years!
So I wish I had discovered "svn blame" long ago, but at least I can happily use "git blame" now. Furthermore, for those PLplot developers not yet aware of the "git blame" command, it is well worth trying now on your own so you can get a feel for how useful it can be when we have a git history that goes back to 1992. In this case, it turned out the line in question was actually committed by me in 2002 and has quietly been working well ever since. The point was to do exactly what it says for those cases when a bunch of different python examples are strung together as one giant script, and this restore of cmap1 eliminates cmap1 cross-talk between those scripts. I was concerned that might create a different PostScript file result for Python, but since restore_cmap1 call has been there since 2002 with no issues like that, I have to look elsewhere for the source of the recently introduced one-line diff I am getting between the plsurf3dl Python and C results for example 8.
