Change the cleanup phase for the grep command to free the pathspec
struct that's allocated earlier in the same block, and used just a few
lines earlier.
With "grep hi README.md" valgrind reports a loss of 239 bytes now,
down from 351.
The relevant --num-callers=40 --leak-check=full --show-leak-kinds=all
backtrace is:
[...] 187 (112 direct, 75 indirect) bytes in 1 blocks are definitely lost in loss record 70 of 110

Since pretty much any non-trivial git command leaks because it skips
cleanup are patches in this category even accepted? Worth a try...
