Bad git log behavior with multiple glob path arguments

git log seems to understand globs in the last path argument, and the last path argument only. I didn't see anything in the git log man page expressly saying this was to be expected, but it does seem like it ought to work for all the arguments or none of them.

Here's a little shell script I ended up using to convince myself I wasn't going crazy. I'd expect the same output for all of the git log test, since they all specify (either with globs or not) all the files added to the repository. Alternatively, if globs aren't expected to work, I'd at least expect all the glob tests to return nothing.

Note that glob matching doesn't seem to occur unless '--' is included. I'm not exactly clear on why that is.

What version did you use? We have a fix in the same area, e4ddb05 (tree_entry_interesting: match against all pathspecs - 2014-01-25), and it's in v1.8.5.5 and v1.9.0

do you mean "git log" does not run at all and complains about disambiguation, or it runs but nothing is filtered?

So close! :) 1.8.5.3

It complains about disambiguation:
