invoking `got log' to find the working revision of a file is quite heavy. It takes several seconds to run on some occasions and working in /usr/src is a pain. (usr.bin/diff/diff.c takes _seven_ seconds to get the first log entry.) `got info' instead is quicker since it doesn't have to traverse the history but only parse the fileindex. (usr.bin/diff/diff.c takes one second to compare.) It also avoids an extra `got status' call if the file is added since `got info' succeeds but doesn't print any commit information in that case.

it gets mapped to the new `got commit -A' flag and overrides the author.

in this case the dolist is shorter and easier to read / reason about

otherwise the file-relative-name is computed relatively to the current directory (i.e. you get back the basename) and vc-got--log fails.

the missing vc-setup-buffer call was preventing it from clearing (at least) the buffer, so the old logs remained.

fix vc-log-search for got from latest -main branch and for future versions. `got log' changed the flag for search from -s to -S (-s is now to select the short log format.) Support for older got version will be kept for the next few (got) releases.
